+# Animation Design Thinking
+
+How to decide WHAT to animate and HOW to structure it — before writing any code.
+
+## Should I animate this?
+
+Not everything benefits from animation. Motion adds cognitive load. Bad animation is worse than a good static diagram.
+
+**Animate when:**
+- A sequence unfolds over time (algorithm steps, derivation, pipeline stages)
+- Spatial relationships change (transformation, deformation, rotation)
+- Something is built from parts (construction, assembly, accumulation)
+- You're comparing states (before/after, method A vs method B)
+- Temporal evolution is the point (training curves, wave propagation, gradient descent)
+
+**Show static when:**
+- The concept is a single labeled diagram (circuit, anatomy, architecture overview)
+- Motion would distract from spatial layout
+- The viewer needs to study it carefully (dense table, reference chart)
+- The concept is already intuitive from a well-labeled figure
+
+**Rule of thumb:** If you'd explain it with "first X, then Y, then Z" — animate it. If you'd explain it by pointing at parts of one picture — show it static.
+
+## Decomposing a concept into animation
+
+### Step 1: Write the narration first
+
+Before any code, write what the narrator would say. This determines:
+- **Order** — what concept comes first
+- **Duration** — how long each idea gets
+- **Visuals** — what the viewer must SEE when they HEAR each sentence
+
+A scene where the narration says "the gradient points uphill" must show a gradient arrow at that moment. If the visual doesn't match the audio, the viewer's brain splits attention and both tracks are lost.
+
+### Step 2: Identify visual beats
+
+A "beat" is a moment where something changes on screen. Mark each beat in your narration:

+"Consider a function f of x."         → [BEAT: axes + curve appear]
+"At this point..."                     → [BEAT: dot appears on curve]
+"...the slope is positive."            → [BEAT: tangent line drawn]
+"So the gradient tells us to go left." → [BEAT: arrow points left, dot moves]
+```
+
+Each beat is one `self.play()` call or a small group of simultaneous animations.
+
+### Step 3: Choose the right tool per beat
+
+| Visual need | Manim approach |
+|-------------|----------------|
+| Object appears for first time | `Create`, `Write`, `FadeIn`, `GrowFromCenter` |
+| Object transforms into another | `Transform`, `ReplacementTransform`, `FadeTransform` |
+| Attention drawn to existing object | `Indicate`, `Circumscribe`, `Flash`, `ShowPassingFlash` |
+| Continuous relationship maintained | `add_updater`, `always_redraw`, `ValueTracker` |
+| Object leaves the scene | `FadeOut`, `Uncreate`, `ShrinkToCenter` |
+| Static context that stays visible | `self.add()` (no animation) |
+
+## Pacing: the universal mistake is too fast
+
+### Timing rules
+
+| Content type | Minimum on-screen time |
+|-------------|----------------------|
+| New equation appearing | 2.0s animation + 2.0s pause |
+| New concept label | 1.0s animation + 1.0s pause |
+| Key insight ("aha moment") | 2.5s animation + 3.0s pause |
+| Supporting annotation | 0.8s animation + 0.5s pause |
+| Scene transition (FadeOut all) | 0.5s animation + 0.3s pause |
+
+### Breathing room
+
+After every reveal, add `self.wait()`. The viewer needs time to:
+1. Read the new text
+2. Connect it to what's already on screen
+3. Form an expectation about what comes next
+
+**No wait = the viewer is always behind you.** They're still reading the equation when you've already started transforming it.
+
+### Tempo variation
+
+Monotonous pacing feels like a lecture. Vary the tempo:
+- **Slow build** for core concepts (long run_time, long pauses)
+- **Quick succession** for supporting details (short run_time, minimal pauses)
+- **Dramatic pause** before the key reveal (extra `self.wait(2.0)` before the "aha")
+- **Rapid montage** for "and this applies to X, Y, Z..." sequences (`LaggedStart` with tight lag_ratio)
+
+## Narration synchronization
+
+### The "see then hear" principle
+
+The visual should appear slightly BEFORE the narration describes it. When the viewer sees a circle appear and THEN hears "consider a circle," the visual primes their brain for the concept. The reverse — hearing first, seeing second — creates confusion because they're searching the screen for something that isn't there yet.
+
+### Practical timing
+
+```python
+# Scene duration should match narration duration.
+# If narration for this scene is 8 seconds:
+# Total animation run_times + total self.wait() times = ~8 seconds.
+
+# Use manim-voiceover for automatic sync:
+with self.voiceover(text="The gradient points downhill") as tracker:
+    self.play(GrowArrow(gradient_arrow), run_time=tracker.duration)
+```
+
+## Equation decomposition strategy
+
+### The "dim and reveal" pattern
+
+When building a complex equation step by step:
+1. Show the full equation dimmed at `opacity=0.2` (sets expectation for where you're going)
+2. Highlight the first term at full opacity
+3. Explain it
+4. Highlight the next term, dim the first to `0.5` (it's now context)
+5. Repeat until the full equation is bright
+
+This is better than building left-to-right because the viewer always sees the destination.
+
+### Term ordering
+
+Animate terms in the order the viewer needs to understand them, not in the order they appear in the equation. For `E = mc²`:
+- Show `E` (the thing we want to know)
+- Then `m` (the input)
+- Then `c²` (the constant that makes it work)
+- Then the `=` (connecting them)
+
+## Architecture and pipeline diagrams
+
+### Box granularity
+
+The most common mistake: too many boxes. Each box is a concept the viewer must track. Five boxes with clear labels beats twelve boxes with abbreviations.
+
+**Rule:** If two consecutive boxes could be labeled "X" and "process X output," merge them into one box.
+
+### Animation strategy
+
+Build pipelines left-to-right (or top-to-bottom) with arrows connecting them:
+1. First box appears alone → explain it
+2. Arrow grows from first to second → "the output feeds into..."
+3. Second box appears → explain it
+4. Repeat
+
+Then show data flowing through: `ShowPassingFlash` along the arrows, or a colored dot traversing the path.
+
+### The zoom-and-return pattern
+
+For complex systems:
+1. Show the full overview (all boxes, small)
+2. Zoom into one box (`MovingCameraScene.camera.frame.animate`)
+3. Expand that box into its internal components
+4. Zoom back out to the overview
+5. Zoom into the next box
+
+## Common design mistakes
+
+1. **Animating everything at once.** The viewer can track 1-2 simultaneous animations. More than that and nothing registers.
+2. **No visual hierarchy.** Everything at the same opacity/size/color means nothing stands out. Use opacity layering.
+3. **Equations without context.** An equation appearing alone means nothing. Always show the geometric/visual interpretation first or simultaneously.
+4. **Skipping the "why."** Showing HOW a transformation works without WHY it matters. Add a sentence/label explaining the purpose.
+5. **Identical pacing throughout.** Every animation at run_time=1.5, every wait at 1.0. Vary it.
+6. **Forgetting the audience.** A video for high schoolers needs different pacing and complexity than one for PhD students. Decide the audience in the planning phase.

+
+## Reactive Mobjects: always_redraw()
+
+Rebuild a mobject from scratch every frame — essential when its geometry depends on other animated objects:
+
+```python
+# Brace that follows a resizing square
+brace = always_redraw(Brace, square, UP)
+self.add(brace)
+self.play(square.animate.scale(2))  # brace auto-adjusts
+
+# Horizontal line that tracks a moving dot
+h_line = always_redraw(lambda: axes.get_h_line(dot.get_left()))
+
+# Label that always stays next to another mobject
+label = always_redraw(lambda: Text("here", font_size=20).next_to(dot, UP, buff=0.2))
+```
+
+Note: `always_redraw` recreates the mobject every frame. For simple property tracking, use `add_updater` instead (cheaper):
+```python
+label.add_updater(lambda m: m.next_to(dot, UP))
+```
+
+## TracedPath — Trajectory Tracing
+
+Draw the path a point has traveled:
+
+```python
+dot = Dot(color=YELLOW)
+path = TracedPath(dot.get_center, stroke_color=YELLOW, stroke_width=2)
+self.add(dot, path)
+self.play(dot.animate.shift(RIGHT * 3 + UP * 2), run_time=2)
+# path shows the trail the dot left behind
+
+# Fading trail (dissipates over time):
+path = TracedPath(dot.get_center, dissipating_time=0.5, stroke_opacity=[0, 1])
+```
+
+Use cases: gradient descent paths, planetary orbits, function tracing, particle trajectories.
+
+## FadeTransform — Smoother Cross-Fades
+
+`Transform` morphs shapes through ugly intermediate warping. `FadeTransform` cross-fades with position matching — use it when source and target look different:
+
+```python
+# UGLY: Transform warps circle into square through a blob
+self.play(Transform(circle, square))
+
+# SMOOTH: FadeTransform cross-fades cleanly
+self.play(FadeTransform(circle, square))
+
+# FadeTransformPieces: per-submobject FadeTransform
+self.play(FadeTransformPieces(group1, group2))
+
+# TransformFromCopy: animate a COPY while keeping the original visible
+self.play(TransformFromCopy(source, target))
+# source stays on screen, a copy morphs into target
+```
+
+**Recommendation:** Use `FadeTransform` as default for dissimilar shapes. Use `Transform`/`ReplacementTransform` only for similar shapes (circle→ellipse, equation→equation).
+
+## ApplyMatrix — Linear Transformation Visualization
+
+Animate a matrix transformation on mobjects:
+
+```python
+# Apply a 2x2 matrix to a grid
+matrix = [[2, 1], [1, 1]]
+self.play(ApplyMatrix(matrix, number_plane), run_time=2)
+
+# Also works on individual mobjects
+self.play(ApplyMatrix([[0, -1], [1, 0]], square))  # 90-degree rotation
+```
+
+Pairs with `LinearTransformationScene` — see `camera-and-3d.md`.
+
+## squish_rate_func — Time-Window Staggering
+
+Compress any rate function into a time window within an animation. Enables overlapping stagger without `LaggedStart`:
+
+```python
+self.play(
+    FadeIn(a, rate_func=squish_rate_func(smooth, 0, 0.5)),    # 0% to 50%
+    FadeIn(b, rate_func=squish_rate_func(smooth, 0.25, 0.75)), # 25% to 75%
+    FadeIn(c, rate_func=squish_rate_func(smooth, 0.5, 1.0)),  # 50% to 100%
+    run_time=2
+)
+```
+
+More precise than `LaggedStart` when you need exact overlap control.
+
+## Additional Rate Functions
+
+```python
+from manim import (
+    smooth, linear, rush_into, rush_from,
+    there_and_back, there_and_back_with_pause,
+    running_start, double_smooth, wiggle,
+    lingering, exponential_decay, not_quite_there,
+    squish_rate_func
+)
+
+# running_start: pulls back before going forward (anticipation)
+self.play(FadeIn(mob, rate_func=running_start))
+
+# there_and_back_with_pause: goes there, holds, comes back
+self.play(mob.animate.shift(UP), rate_func=there_and_back_with_pause)
+
+# not_quite_there: stops at a fraction of the full animation
+self.play(FadeIn(mob, rate_func=not_quite_there(0.7)))
+```
+
+## ShowIncreasingSubsets / ShowSubmobjectsOneByOne
+
+Reveal group members progressively — ideal for algorithm visualization:
+
+```python
+# Reveal array elements one at a time
+array = Group(*[Square() for _ in range(8)]).arrange(RIGHT)
+self.play(ShowIncreasingSubsets(array), run_time=3)
+
+# Show submobjects with staggered appearance
+self.play(ShowSubmobjectsOneByOne(code_lines), run_time=4)
+```
+
+## ShowPassingFlash
+
+A flash of light travels along a path:
+
+```python
+# Flash traveling along a curve
+self.play(ShowPassingFlash(curve.copy().set_color(YELLOW), time_width=0.3))
+

+# Decorations and Visual Polish
+
+Decorations are mobjects that annotate, highlight, or frame other mobjects. They turn a technically correct animation into a visually polished one.
+
+## SurroundingRectangle
+
+Draws a rectangle around any mobject. The go-to for highlighting:
+
+```python
+highlight = SurroundingRectangle(
+    equation[2],            # the term to highlight
+    color=YELLOW,
+    buff=0.15,              # padding between content and border
+    corner_radius=0.1,      # rounded corners
+    stroke_width=2
+)
+self.play(Create(highlight))
+self.wait(1)
+self.play(FadeOut(highlight))
+```
+
+### Around part of an equation
+
+```python
+eq = MathTex(r"E", r"=", r"m", r"c^2")
+box = SurroundingRectangle(eq[2:], color=YELLOW, buff=0.1)  # highlight "mc²"
+label = Text("mass-energy", font_size=18, font="Menlo", color=YELLOW)
+label.next_to(box, DOWN, buff=0.2)
+self.play(Create(box), FadeIn(label))
+```
+
+## BackgroundRectangle
+
+Semi-transparent background behind text for readability over complex scenes:
+
+```python
+bg = BackgroundRectangle(equation, fill_opacity=0.7, buff=0.2, color=BLACK)
+self.play(FadeIn(bg), Write(equation))
+
+# Or using set_stroke for a "backdrop" effect on the text itself:
+label.set_stroke(BLACK, width=5, background=True)
+```
+
+The `set_stroke(background=True)` approach is cleaner for text labels over graphs/diagrams.
+
+## Brace and BraceLabel
+
+Curly braces that annotate sections of a diagram or equation:
+
+```python
+brace = Brace(equation[2:4], DOWN, color=YELLOW)
+brace_label = brace.get_text("these terms", font_size=20)
+self.play(GrowFromCenter(brace), FadeIn(brace_label))
+
+# Between two specific points
+brace = BraceBetweenPoints(point_a, point_b, direction=UP)
+```
+
+### Brace placement
+
+```python
+# Below a group
+Brace(group, DOWN)
+# Above a group
+Brace(group, UP)
+# Left of a group
+Brace(group, LEFT)
+# Right of a group
+Brace(group, RIGHT)
+```
+
+## Arrows for Annotation
+
+### Straight arrows pointing to mobjects
+
+```python
+arrow = Arrow(
+    start=label.get_bottom(),
+    end=target.get_top(),
+    color=YELLOW,
+    stroke_width=2,
+    buff=0.1,                    # gap between arrow tip and target
+    max_tip_length_to_length_ratio=0.15  # small arrowhead
+)
+self.play(GrowArrow(arrow), FadeIn(label))
+```
+
+### Curved arrows
+
+```python
+arrow = CurvedArrow(
+    start_point=source.get_right(),
+    end_point=target.get_left(),
+    angle=PI/4,                  # curve angle
+    color=PRIMARY
+)
+```
+
+### Labeling with arrows
+
+```python
+# LabeledArrow: arrow with built-in text label
+arr = LabeledArrow(
+    Text("gradient", font_size=16, font="Menlo"),
+    start=point_a, end=point_b, color=RED
+)
+```
+
+## DashedLine and DashedVMobject
+
+```python
+# Dashed line (for asymptotes, construction lines, implied connections)
+asymptote = DashedLine(
+    axes.c2p(2, -3), axes.c2p(2, 3),
+    color=YELLOW, dash_length=0.15
+)
+
+# Make any VMobject dashed
+dashed_circle = DashedVMobject(Circle(radius=2, color=BLUE), num_dashes=30)
+```
+
+## Angle and RightAngle Markers
+
+```python
+line1 = Line(ORIGIN, RIGHT * 2)
+line2 = Line(ORIGIN, UP * 2 + RIGHT)
+
+# Angle arc between two lines
+angle = Angle(line1, line2, radius=0.5, color=YELLOW)
+angle_value = angle.get_value()  # radians
+
+# Right angle marker (the small square)
+right_angle = RightAngle(line1, Line(ORIGIN, UP * 2), length=0.3, color=WHITE)
+```
+
+## Cross (strikethrough)
+
+Mark something as wrong or deprecated:
+
+```python
+cross = Cross(old_equation, color=RED, stroke_width=4)
+self.play(Create(cross))
+# Then show the correct version
+```
+
+## Underline
+
+```python
+underline = Underline(important_text, color=ACCENT, stroke_width=3)
+self.play(Create(underline))
+```
+
+## Color Highlighting Workflow
+
+### Method 1: At creation with t2c
+
+```python
+text = Text("The gradient is negative here", t2c={"gradient": BLUE, "negative": RED})
+```
+
+### Method 2: set_color_by_tex after creation
+
+```python
+eq = MathTex(r"\nabla L = -\frac{\partial L}{\partial w}")
+eq.set_color_by_tex(r"\nabla", BLUE)
+eq.set_color_by_tex(r"\partial", RED)
+```
+
+### Method 3: Index into submobjects
+
+```python
+eq = MathTex(r"a", r"+", r"b", r"=", r"c")
+eq[0].set_color(RED)    # "a"
+eq[2].set_color(BLUE)   # "b"
+eq[4].set_color(GREEN)  # "c"
+```
+
+## Combining Annotations
+
+Layer multiple annotations for emphasis:
+
+```python
+# Highlight a term, add a brace, and an arrow — in sequence
+box = SurroundingRectangle(eq[2], color=YELLOW, buff=0.1)
+brace = Brace(eq[2], DOWN, color=YELLOW)
+label = brace.get_text("learning rate", font_size=18)
+
+self.play(Create(box))
+self.wait(0.5)
+self.play(FadeOut(box), GrowFromCenter(brace), FadeIn(label))
+self.wait(1.5)
+self.play(FadeOut(brace), FadeOut(label))
+```
+
+### The annotation lifecycle
+
+Annotations should follow a rhythm:
+1. **Appear** — draw attention (Create, GrowFromCenter)
+2. **Hold** — viewer reads and understands (self.wait)
+3. **Disappear** — clear the stage for the next thing (FadeOut)
+
+Never leave annotations on screen indefinitely — they become visual noise once their purpose is served.

+## substrings_to_isolate for Complex Equations
+
+For dense equations where manually splitting into parts is impractical, use `substrings_to_isolate` to tell Manim which substrings to track as individual elements:
+
+```python
+# Without isolation — the whole expression is one blob
+lagrangian = MathTex(
+    r"\mathcal{L} = \bar{\psi}(i \gamma^\mu D_\mu - m)\psi - \tfrac{1}{4}F_{\mu\nu}F^{\mu\nu}"
+)
+
+# With isolation — each named substring is a separate submobject
+lagrangian = MathTex(
+    r"\mathcal{L} = \bar{\psi}(i \gamma^\mu D_\mu - m)\psi - \tfrac{1}{4}F_{\mu\nu}F^{\mu\nu}",
+    substrings_to_isolate=[r"\psi", r"D_\mu", r"\gamma^\mu", r"F_{\mu\nu}"]
+)
+# Now you can color individual terms
+lagrangian.set_color_by_tex(r"\psi", BLUE)
+lagrangian.set_color_by_tex(r"F_{\mu\nu}", YELLOW)
+```
+
+Essential for `TransformMatchingTex` on complex equations — without isolation, matching fails on dense expressions.
+
+## Multi-Line Complex Equations
+
+For equations with multiple related lines, pass each line as a separate argument:
+
+```python
+maxwell = MathTex(
+    r"\nabla \cdot \mathbf{E} = \frac{\rho}{\epsilon_0}",
+    r"\nabla \times \mathbf{B} = \mu_0\mathbf{J} + \mu_0\epsilon_0\frac{\partial \mathbf{E}}{\partial t}"
+).arrange(DOWN)
+
+# Each line is a separate submobject — animate independently
+self.play(Write(maxwell[0]))
+self.wait(1)
+self.play(Write(maxwell[1]))
+```
+
+## TransformMatchingTex with key_map
+
+Map specific substrings between source and target equations during transformation:
+
+```python

+eq2 = MathTex(r"A^2 = C^2 - B^2")
+
+self.play(TransformMatchingTex(
+    eq1, eq2,
+    key_map={"+": "-"},   # map "+" in source to "-" in target
+    path_arc=PI / 2,      # arc the pieces into position
+))
+```
+
+## set_color_by_tex — Color by Substring
+
+```python

+eq.set_color_by_tex("E", BLUE)
+eq.set_color_by_tex("m", RED)
+eq.set_color_by_tex("c", GREEN)
+```
+
+## TransformMatchingTex with matched_keys
+
+When matching substrings are ambiguous, specify which to align explicitly:
+
+```python
+kw = dict(font_size=72, t2c={"A": BLUE, "B": TEAL, "C": GREEN})
+lines = [
+    MathTex(r"A^2 + B^2 = C^2", **kw),
+    MathTex(r"A^2 = C^2 - B^2", **kw),
+    MathTex(r"A^2 = (C + B)(C - B)", **kw),
+    MathTex(r"A = \sqrt{(C + B)(C - B)}", **kw),
+]
+
+self.play(TransformMatchingTex(
+    lines[0].copy(), lines[1],
+    matched_keys=["A^2", "B^2", "C^2"],  # explicitly match these

+    path_arc=PI / 2,                       # arc pieces into position
+))
+```
+
+Without `matched_keys`, the animation matches the longest common substrings, which can produce unexpected results on complex equations (e.g., "^2 = C^2" matching across terms).

+# Angle marker between two lines

+
+## Boolean Operations (CSG)
+

+intersect = Intersection(circle, square, color=YELLOW, fill_opacity=0.5)
+diff = Difference(circle, square, color=PURPLE, fill_opacity=0.5)
+exclude = Exclusion(circle, square, color=ORANGE, fill_opacity=0.5)
+```
+
+Use cases: Venn diagrams, set theory, geometric proofs, area calculations.
+
+## LabeledArrow / LabeledLine
+
+```python
+# Arrow with built-in label (auto-positioned)
+arr = LabeledArrow(Text("force", font_size=18), start=LEFT, end=RIGHT, color=RED)
+
+# Line with label
+line = LabeledLine(Text("d = 5m", font_size=18), start=LEFT * 2, end=RIGHT * 2)
+```
+
+Auto-handles label positioning — cleaner than manual `Arrow` + `Text().next_to()`.
+
+## Text Color/Font/Style Per-Substring (t2c, t2f, t2s, t2w)
+
+```python
+# Color specific words (t2c = text-to-color)
+text = Text(
+    "Gradient descent minimizes the loss function",
+    t2c={"Gradient descent": BLUE, "loss function": RED}
+)
+
+# Different fonts per word (t2f = text-to-font)
+text = Text(
+    "Use Menlo for code and Inter for prose",
+    t2f={"Menlo": "Menlo", "Inter": "Inter"}
+)
+
+# Italic/slant per word (t2s = text-to-slant)
+text = Text("Normal and italic text", t2s={"italic": ITALIC})
+
+# Bold per word (t2w = text-to-weight)
+text = Text("Normal and bold text", t2w={"bold": BOLD})
+```
+
+These are much cleaner than creating separate Text objects and grouping them.
+
+## Backstroke for Readability Over Backgrounds
+
+When text overlaps other content (graphs, diagrams, images), add a dark stroke behind it:
+
+```python
+# CE syntax:
+label.set_stroke(BLACK, width=5, background=True)
+
+# Apply to a group
+for mob in labels:
+    mob.set_stroke(BLACK, width=4, background=True)
+```
+
+This is how 3Blue1Brown keeps text readable over complex backgrounds without using BackgroundRectangle.
+
+## Complex Function Transforms
+
+Apply complex functions to entire mobjects — transforms the plane:
+
+```python
+c_grid = ComplexPlane()
+moving_grid = c_grid.copy()
+moving_grid.prepare_for_nonlinear_transform()  # adds more sample points for smooth deformation
+
+self.play(
+    moving_grid.animate.apply_complex_function(lambda z: z**2),
+    run_time=5,
+)
+
+# Also works with R3->R3 functions:
+self.play(grid.animate.apply_function(
+    lambda p: [p[0] + 0.5 * math.sin(p[1]), p[1] + 0.5 * math.sin(p[0]), p[2]]
+), run_time=5)
+```
+
+**Critical:** Call `prepare_for_nonlinear_transform()` before applying nonlinear functions — without it, the grid has too few sample points and the deformation looks jagged.

+# Paper Explainer Workflow
+
+How to turn a research paper into an animated explainer video.
+
+## Why animate a paper?
+
+A research paper is optimized for precision and completeness. A video is optimized for understanding and retention. The translation is NOT "read the paper aloud with pictures" — it's "extract the core insight and make it feel obvious through visual storytelling."
+
+The paper has one job: prove the claim is true. The video has a different job: make the viewer understand WHY the claim is true, and WHY it matters.
+
+## Who is watching?
+
+Before anything, decide the audience:
+
+| Audience | Prerequisites | Pacing | Depth |
+|----------|--------------|--------|-------|
+| General public | None | Slow, many analogies | Intuition only, skip proofs |
+| Undergrad students | Basic math/CS | Medium, some formalism | Key equations, skip derivations |
+| Grad students / researchers | Domain knowledge | Faster, more notation | Full equations, sketch proofs |
+
+This determines everything: vocabulary, pacing, which sections to animate, how much math to show.
+
+## The 5-minute template
+
+Most paper explainers fit this structure (scale times proportionally for longer videos):
+
+| Section | Duration | Purpose |
+|---------|----------|---------|
+| **Hook** | 0:00-0:30 | Surprising result or provocative question |
+| **Problem** | 0:30-1:30 | What was broken/missing before this paper |
+| **Key insight** | 1:30-3:00 | The core idea, explained visually |
+| **How it works** | 3:00-4:00 | Method/algorithm, simplified |
+| **Evidence** | 4:00-4:30 | Key result that proves it works |
+| **Implications** | 4:30-5:00 | Why it matters, what it enables |
+
+### What to skip
+
+- Related work survey → one sentence: "Previous approaches did X, which had problem Y"
+- Implementation details → skip unless they're the contribution
+- Ablation studies → show one chart at most
+- Proofs → show the key step, not the full proof
+- Hyperparameter tuning → skip entirely
+
+### What to expand
+
+- The core insight → this gets the most screen time
+- Geometric/visual intuition → if the paper has math, show what it MEANS
+- Before/after comparison → the most compelling evidence
+
+## Pre-code workflow
+
+### Gate 1: Narration script
+
+Write the full narration before any code. Every sentence maps to a visual beat. If you can't write the narration, you don't understand the paper well enough to animate it.
+
+```markdown
+## Hook (30s)
+"What if I told you that a model with 7 billion parameters can outperform
+one with 70 billion — if you train it on the right data?"
+
+## Problem (60s)
+"The standard approach is to scale up. More parameters, more compute.
+[VISUAL: bar chart showing model sizes growing exponentially]
+But Chinchilla showed us that most models are undertrained..."
+```
+
+### Gate 2: Scene list
+
+After the narration, break it into scenes. Each scene is one Manim class.
+
+```markdown
+Scene 1: Hook — surprising stat with animated counter
+Scene 2: Problem — model size bar chart growing
+Scene 3: Key insight — training data vs parameters, animated 2D plot
+Scene 4: Method — pipeline diagram building left to right
+Scene 5: Results — before/after comparison with animated bars
+Scene 6: Closing — implications text
+```
+
+### Gate 3: Style constants
+
+Before coding scenes, define the visual language:
+
+```python
+# style.py — import in every scene file
+BG = "#0D1117"
+PRIMARY = "#58C4DD"
+SECONDARY = "#83C167"
+ACCENT = "#FFFF00"
+HIGHLIGHT = "#FF6B6B"
+MONO = "Menlo"
+
+# Color meanings for THIS paper
+MODEL_COLOR = PRIMARY      # "the model"
+DATA_COLOR = SECONDARY     # "training data"
+BASELINE_COLOR = HIGHLIGHT # "previous approach"
+RESULT_COLOR = ACCENT      # "our result"
+```
+
+## First-principles equation explanation
+
+When the paper has a key equation, don't just show it — build it from intuition:
+
+### The "what would you do?" pattern
+
+1. Pose the problem in plain language
+2. Ask what the simplest solution would be
+3. Show why it doesn't work (animate the failure)
+4. Introduce the paper's solution as the fix
+5. THEN show the equation — it now feels earned
+
+```python
+# Scene: Why we need attention (for a Transformer paper)
+# Step 1: "How do we let each word look at every other word?"
+# Step 2: Show naive approach (fully connected = O(n²) everything)
+# Step 3: Show it breaks (information overload, no selectivity)
+# Step 4: "What if each word could CHOOSE which words to attend to?"
+# Step 5: Show attention equation — Q, K, V now mean something
+```
+
+### Equation reveal strategy
+
+```python
+# Show equation dimmed first (full destination)
+eq = MathTex(r"Attention(Q,K,V) = softmax\left(\frac{QK^T}{\sqrt{d_k}}\right)V")
+eq.set_opacity(0.15)
+self.play(FadeIn(eq))
+
+# Highlight Q, K, V one at a time with color + label
+for part, color, label_text in [
+    (r"Q", PRIMARY, "Query: what am I looking for?"),
+    (r"K", SECONDARY, "Key: what do I contain?"),
+    (r"V", ACCENT, "Value: what do I output?"),
+]:
+    eq.set_color_by_tex(part, color)
+    label = Text(label_text, font_size=18, color=color, font=MONO)
+    # position label, animate it, wait, then dim it
+```
+
+## Building architecture diagrams
+
+### The progressive build pattern
+
+Don't show the full architecture at once. Build it:
+
+1. First component appears alone → explain
+2. Arrow grows → "this feeds into..."
+3. Second component appears → explain
+4. Repeat until complete
+
+```python
+# Component factory
+def make_box(label, color, width=2.0, height=0.8):
+    box = RoundedRectangle(corner_radius=0.1, width=width, height=height,
+                           color=color, fill_opacity=0.1, stroke_width=1.5)
+    text = Text(label, font_size=18, font=MONO, color=color).move_to(box)
+    return Group(box, text)
+
+encoder = make_box("Encoder", PRIMARY)
+decoder = make_box("Decoder", SECONDARY).next_to(encoder, RIGHT, buff=1.5)
+arrow = Arrow(encoder.get_right(), decoder.get_left(), color=DIM, stroke_width=1.5)
+
+self.play(FadeIn(encoder))
+self.wait(1)  # explain encoder
+self.play(GrowArrow(arrow))
+self.play(FadeIn(decoder))
+self.wait(1)  # explain decoder
+```
+
+### Data flow animation
+
+After building the diagram, show data moving through it:
+
+```python
+# Dot traveling along the pipeline
+data_dot = Dot(color=ACCENT, radius=0.1).move_to(encoder)
+self.play(FadeIn(data_dot))
+self.play(MoveAlongPath(data_dot, arrow), run_time=1)
+self.play(data_dot.animate.move_to(decoder), run_time=0.5)
+self.play(Flash(data_dot.get_center(), color=ACCENT), run_time=0.3)
+```
+
+## Animating results
+
+### Bar chart comparison (most common)
+
+```python
+# Before/after bars
+before_data = [45, 52, 38, 61]
+after_data = [78, 85, 72, 91]
+labels = ["Task A", "Task B", "Task C", "Task D"]
+
+before_chart = BarChart(before_data, bar_names=labels,
+    y_range=[0, 100, 20], bar_colors=[HIGHLIGHT]*4).scale(0.6).shift(LEFT*3)
+after_chart = BarChart(after_data, bar_names=labels,
+    y_range=[0, 100, 20], bar_colors=[SECONDARY]*4).scale(0.6).shift(RIGHT*3)
+
+before_label = Text("Baseline", font_size=20, color=HIGHLIGHT, font=MONO)
+after_label = Text("Ours", font_size=20, color=SECONDARY, font=MONO)
+
+# Reveal baseline first, then ours (dramatic comparison)
+self.play(Create(before_chart), FadeIn(before_label))
+self.wait(1.5)
+self.play(Create(after_chart), FadeIn(after_label))
+self.wait(0.5)
+
+# Highlight the improvement
+improvement = Text("+35% avg", font_size=24, color=ACCENT, font=MONO)
+self.play(FadeIn(improvement))
+```
+
+### Training curve (for ML papers)
+
+```python
+tracker = ValueTracker(0)
+curve = always_redraw(lambda: axes.plot(
+    lambda x: 1 - 0.8 * np.exp(-x / 3),
+    x_range=[0, tracker.get_value()], color=PRIMARY
+))
+epoch_label = always_redraw(lambda: Text(
+    f"Epoch {int(tracker.get_value())}", font_size=18, font=MONO
+).to_corner(UR))
+
+self.add(curve, epoch_label)
+self.play(tracker.animate.set_value(10), run_time=5, rate_func=linear)
+```
+
+## Domain-specific patterns
+
+### ML papers
+- Show data flow through the model (animated pipeline)
+- Training curves with `ValueTracker`
+- Attention heatmaps as colored grids
+- Embedding space as 2D scatter (PCA/t-SNE visualization)
+- Loss landscape as 3D surface with gradient descent dot
+
+### Physics/math papers
+- Use `LinearTransformationScene` for linear algebra
+- Vector fields with `ArrowVectorField` / `StreamLines`
+- Phase spaces with `NumberPlane` + trajectories
+- Wave equations with time-parameterized plots
+
+### Systems/architecture papers
+- Pipeline diagrams built progressively
+- `ShowPassingFlash` for data flow along arrows
+- `ZoomedScene` for zooming into components
+- Before/after latency/throughput comparisons
+
+## Common mistakes
+
+1. **Trying to cover the whole paper.** A 5-minute video can explain ONE core insight well. Covering everything means explaining nothing.
+2. **Reading the abstract as narration.** Academic writing is designed for readers, not listeners. Rewrite in conversational language.
+3. **Showing notation without meaning.** Never show a symbol without first showing what it represents visually.
+4. **Skipping the motivation.** Jumping straight to "here's our method" without showing why the problem matters. The Problem section is what makes the viewer care.
+5. **Identical pacing throughout.** The hook and key insight need the most visual energy. The method section can be faster. Evidence should land with impact (pause after showing the big number).

+# Production Quality Checklist
+
+Standards and checks for ensuring animation output is publication-ready.
+
+## Pre-Code Checklist
+
+Before writing any Manim code:
+
+- [ ] Narration script written with visual beats marked
+- [ ] Scene list with purpose, duration, and layout for each
+- [ ] Color palette defined with meaning assignments (`PRIMARY` = main concept, etc.)
+- [ ] `MONO = "Menlo"` set as the font constant
+- [ ] Target resolution and aspect ratio decided
+
+## Text Quality
+
+### Overlap prevention
+
+```python
+# RULE: buff >= 0.5 for edge text
+label.to_edge(DOWN, buff=0.5)     # GOOD
+label.to_edge(DOWN, buff=0.3)     # BAD — may clip
+
+# RULE: FadeOut previous before adding new at same position
+self.play(ReplacementTransform(note1, note2))  # GOOD
+self.play(Write(note2))                          # BAD — overlaps note1
+
+# RULE: Reduce font size for dense scenes
+# When > 4 text elements visible, use font_size=20 not 28
+```
+
+### Width enforcement
+
+Long text strings overflow the frame:
+
+```python
+# RULE: Set max width for any text that might be long
+text = Text("This is a potentially long description", font_size=22, font=MONO)
+if text.width > config.frame_width - 1.0:
+    text.set_width(config.frame_width - 1.0)
+```
+
+### Font consistency
+
+```python
+# RULE: Define MONO once, use everywhere
+MONO = "Menlo"
+
+# WRONG: mixing fonts
+Text("Title", font="Helvetica")
+Text("Label", font="Arial")
+Text("Code", font="Courier")
+
+# RIGHT: one font
+Text("Title", font=MONO, weight=BOLD, font_size=48)
+Text("Label", font=MONO, font_size=20)
+Text("Code", font=MONO, font_size=18)
+```
+
+## Spatial Layout
+
+### The coordinate budget
+
+The visible frame is approximately 14.2 wide × 8.0 tall (default 16:9). With mandatory margins:
+
+```
+Usable area: x ∈ [-6.5, 6.5], y ∈ [-3.5, 3.5]
+Top title zone: y ∈ [2.5, 3.5]
+Bottom note zone: y ∈ [-3.5, -2.5]
+Main content: y ∈ [-2.5, 2.5], x ∈ [-6.0, 6.0]
+```
+
+### Fill the frame
+
+Empty scenes look unfinished. If the main content is small, add context:
+- A dimmed grid/axes behind the content
+- A title/subtitle at the top
+- A source citation at the bottom
+- Decorative geometry at low opacity
+
+### Maximum simultaneous elements
+
+**Hard limit: 6 actively visible elements.** Beyond that, the viewer can't track everything. If you need more:
+- Dim old elements to opacity 0.3
+- Remove elements that have served their purpose
+- Split into two scenes
+
+## Animation Quality
+
+### Variety audit
+
+Check that no two consecutive scenes use the exact same:
+- Animation type (if Scene 3 uses Write for everything, Scene 4 should use FadeIn or Create)
+- Color emphasis (rotate through palette colors)
+- Layout (center, left-right, grid — alternate)
+- Pacing (if Scene 2 was slow and deliberate, Scene 3 can be faster)
+
+### Tempo curve
+
+A good video follows a tempo curve:
+
+```
+Slow ──→ Medium ──→ FAST (climax) ──→ Slow (conclusion)
+
+Scene 1: Slow (introduction, setup)
+Scene 2: Medium (building understanding)
+Scene 3: Medium-Fast (core content, lots of animation)
+Scene 4: FAST (montage of applications/results)
+Scene 5: Slow (conclusion, key takeaway)
+```
+
+### Transition quality
+
+Between scenes:
+- **Clean exit**: `self.play(FadeOut(Group(*self.mobjects)), run_time=0.5)`
+- **Brief pause**: `self.wait(0.3)` after fadeout, before next scene's first animation
+- **Never hard-cut**: always animate the transition
+
+## Color Quality
+
+### Dimming on dark backgrounds
+
+Colors that look vibrant on white look muddy on dark backgrounds (#0D1117, #1C1C1C). Test your palette:
+
+```python
+# Colors that work well on dark backgrounds:
+# Bright and saturated: #58C4DD, #83C167, #FFFF00, #FF6B6B
+# Colors that DON'T work: #666666 (invisible), #2244AA (too dark)
+
+# RULE: Structural elements (axes, grids) at opacity 0.15
+# Context elements at 0.3-0.4
+# Primary elements at 1.0
+```
+
+### Color meaning consistency
+
+Once a color is assigned a meaning, it keeps that meaning for the entire video:
+
+```python
+# If PRIMARY (#58C4DD) means "the model" in Scene 1,
+# it means "the model" in every scene.
+# Never reuse PRIMARY for a different concept later.
+```
+
+## Data Visualization Quality
+
+### Minimum requirements for charts
+
+- Axis labels on every axis
+- Y-axis range starts at 0 (or has a clear break indicator)
+- Bar/line colors match the legend
+- Numbers on notable data points (at least the maximum and the comparison point)
+
+### Animated counters
+
+When showing a number changing:
+```python
+# GOOD: DecimalNumber with smooth animation
+counter = DecimalNumber(0, font_size=48, num_decimal_places=0, font="Menlo")
+self.play(counter.animate.set_value(1000), run_time=3, rate_func=rush_from)
+
+# BAD: Text that jumps between values
+```
+
+## Pre-Render Checklist
+
+Before running `manim -qh`:
+
+- [ ] All scenes render without errors at `-ql`
+- [ ] Preview stills at `-qm` for text-heavy scenes (check kerning)
+- [ ] Background color set in every scene (`self.camera.background_color = BG`)
+- [ ] `add_subcaption()` or `subcaption=` on every significant animation
+- [ ] No text smaller than font_size=18
+- [ ] No text using proportional fonts (use monospace)
+- [ ] buff >= 0.5 on all `.to_edge()` calls
+- [ ] Clean exit (FadeOut all) at end of every scene
+- [ ] `self.wait()` after every reveal
+- [ ] Color constants used (no hardcoded hex strings in scene code)
+- [ ] All scenes use the same quality flag (don't mix `-ql` and `-qh`)
+
+## Post-Render Checklist
+
+After stitching the final video:
+
+- [ ] Watch the complete video at 1x speed — does it feel rushed anywhere?
+- [ ] Is there a moment where two things animate simultaneously and it's confusing?
+- [ ] Does every text label have enough time to be read?
+- [ ] Are transitions between scenes smooth (no black frames, no jarring cuts)?
+- [ ] Is the audio in sync with the visuals (if using voiceover)?
+- [ ] Is the Gibbs-like "first impression" good? The first 5 seconds determine if someone keeps watching

+Mark sections within a scene for organized output:
+
+```python
+class LongVideo(Scene):
+    def construct(self):
+        self.next_section("Introduction")
+        # ... intro content ...
+
+        self.next_section("Main Concept")
+        # ... main content ...
+
+        self.next_section("Conclusion")
+        # ... closing ...
+```
+
+Render individual sections: `manim --save_sections script.py LongVideo`
+This outputs separate video files per section — useful for long videos where you want to re-render only one part.
+
+## manim-voiceover Plugin (Recommended for Narrated Videos)
+
+The official `manim-voiceover` plugin integrates TTS directly into scene code, auto-syncing animation duration to voiceover length. This is significantly cleaner than the manual ffmpeg muxing approach above.
+
+### Installation
+
+```bash
+pip install "manim-voiceover[elevenlabs]"
+# Or for free/local TTS:
+pip install "manim-voiceover[gtts]"    # Google TTS (free, lower quality)
+pip install "manim-voiceover[azure]"   # Azure Cognitive Services
+```
+
+### Usage
+
+```python
+from manim import *
+from manim_voiceover import VoiceoverScene
+from manim_voiceover.services.elevenlabs import ElevenLabsService
+
+class NarratedScene(VoiceoverScene):
+    def construct(self):
+        self.set_speech_service(ElevenLabsService(
+            voice_name="Alice",
+            model_id="eleven_multilingual_v2"
+        ))
+
+        # Voiceover auto-controls scene duration
+        with self.voiceover(text="Here is a circle being drawn.") as tracker:
+            self.play(Create(Circle()), run_time=tracker.duration)
+
+        with self.voiceover(text="Now let's transform it into a square.") as tracker:
+            self.play(Transform(circle, Square()), run_time=tracker.duration)
+```
+
+### Key Features
+
+- `tracker.duration` — total voiceover duration in seconds
+- `tracker.time_until_bookmark("mark1")` — sync specific animations to specific words
+- Auto-generates subtitle `.srt` files
+- Caches audio locally — re-renders don't re-generate TTS
+- Works with: ElevenLabs, Azure, Google TTS, pyttsx3 (offline), and custom services
+
+### Bookmarks for Precise Sync
+
+```python
+with self.voiceover(text='This is a <bookmark mark="circle"/>circle.') as tracker:
+    self.wait_until_bookmark("circle")
+    self.play(Create(Circle()), run_time=tracker.time_until_bookmark("circle", limit=1))
+```
+
+This is the recommended approach for any video with narration. The manual ffmpeg muxing workflow above is still useful for adding background music or post-production audio mixing.

+# Updaters and Value Trackers
+
+## The problem updaters solve
+
+Normal animations are discrete: `self.play()` goes from state A to state B. But what if you need continuous relationships — a label that always hovers above a moving dot, or a line that always connects two points?
+
+Without updaters, you'd manually reposition every dependent object before every `self.play()`. Five animations that move a dot means five manual repositioning calls for the label. Miss one and it freezes in the wrong spot.
+
+Updaters let you declare a relationship ONCE. Manim calls the updater function EVERY FRAME (15-60 fps depending on quality) to enforce that relationship, no matter what else is happening.
+
+## ValueTracker: an invisible steering wheel
+
+A ValueTracker is an invisible Mobject that holds a single float. It never appears on screen. It exists so you can ANIMATE it while other objects REACT to its value.
+
+Think of it as a slider: drag the slider from 0 to 5, and every object wired to it responds in real time.
+
+```python
+tracker = ValueTracker(0)        # invisible, stores 0.0
+tracker.get_value()              # read: 0.0
+tracker.set_value(5)             # write: jump to 5.0 instantly
+tracker.animate.set_value(5)     # animate: smoothly interpolate to 5.0
+```
+
+### The three-step pattern
+
+Every ValueTracker usage follows this:
+
+1. **Create the tracker** (the invisible slider)
+2. **Create visible objects that READ the tracker** via updaters
+3. **Animate the tracker** — all dependents update automatically
+
+```python
+# Step 1: Create tracker
+x_tracker = ValueTracker(1)
+
+# Step 2: Create dependent objects
+dot = always_redraw(lambda: Dot(axes.c2p(x_tracker.get_value(), 0), color=YELLOW))
+v_line = always_redraw(lambda: axes.get_vertical_line(
+    axes.c2p(x_tracker.get_value(), func(x_tracker.get_value())), color=BLUE
+))
+label = always_redraw(lambda: DecimalNumber(x_tracker.get_value(), font_size=24)
+    .next_to(dot, UP))
+
+self.add(dot, v_line, label)
+
+# Step 3: Animate the tracker — everything follows
+self.play(x_tracker.animate.set_value(5), run_time=3)
+```
+
+## Types of updaters
+
+### Lambda updater (most common)
+
+Runs a function every frame, passing the mobject itself:
+
+```python
+# Label always stays above the dot
+label.add_updater(lambda m: m.next_to(dot, UP, buff=0.2))
+
+# Line always connects two points
+line.add_updater(lambda m: m.put_start_and_end_on(
+    point_a.get_center(), point_b.get_center()
+))
+```
+
+### Time-based updater (with dt)
+
+The second argument `dt` is the time since the last frame (~0.017s at 60fps):
+
+```python
+# Continuous rotation
+square.add_updater(lambda m, dt: m.rotate(0.5 * dt))
+
+# Continuous rightward drift
+dot.add_updater(lambda m, dt: m.shift(RIGHT * 0.3 * dt))
+
+# Oscillation
+dot.add_updater(lambda m, dt: m.move_to(
+    axes.c2p(m.get_center()[0], np.sin(self.time))
+))
+```
+
+Use `dt` updaters for physics simulations, continuous motion, and time-dependent effects.
+
+### always_redraw: full rebuild every frame
+
+Creates a new mobject from scratch each frame. More expensive than `add_updater` but handles cases where the mobject's structure changes (not just position/color):
+
+```python
+# Brace that follows a resizing square
+brace = always_redraw(Brace, square, UP)
+
+# Area under curve that updates as function changes
+area = always_redraw(lambda: axes.get_area(
+    graph, x_range=[0, x_tracker.get_value()], color=BLUE, opacity=0.3
+))
+
+# Label that reconstructs its text
+counter = always_redraw(lambda: Text(
+    f"n = {int(x_tracker.get_value())}", font_size=24, font="Menlo"
+).to_corner(UR))
+```
+
+**When to use which:**
+- `add_updater` — position, color, opacity changes (cheap, preferred)
+- `always_redraw` — when the shape/structure itself changes (expensive, use sparingly)
+
+## DecimalNumber: showing live values
+
+```python
+# Counter that tracks a ValueTracker
+tracker = ValueTracker(0)
+number = DecimalNumber(0, font_size=48, num_decimal_places=1, color=PRIMARY)
+number.add_updater(lambda m: m.set_value(tracker.get_value()))
+number.add_updater(lambda m: m.next_to(dot, RIGHT, buff=0.3))
+
+self.add(number)
+self.play(tracker.animate.set_value(100), run_time=3)
+```
+
+### Variable: the labeled version
+
+```python
+var = Variable(0, Text("x", font_size=24, font="Menlo"), num_decimal_places=2)
+self.add(var)
+self.play(var.tracker.animate.set_value(PI), run_time=2)
+# Displays: x = 3.14
+```
+
+## Removing updaters
+
+```python
+# Remove all updaters
+mobject.clear_updaters()
+
+# Suspend temporarily (during an animation that would fight the updater)
+mobject.suspend_updating()
+self.play(mobject.animate.shift(RIGHT))
+mobject.resume_updating()
+
+# Remove specific updater (if you stored a reference)
+def my_updater(m):
+    m.next_to(dot, UP)
+label.add_updater(my_updater)
+# ... later ...
+label.remove_updater(my_updater)
+```
+
+## Animation-based updaters
+
+### UpdateFromFunc / UpdateFromAlphaFunc
+
+These are ANIMATIONS (passed to `self.play`), not persistent updaters:
+
+```python
+# Call a function on each frame of the animation
+self.play(UpdateFromFunc(mobject, lambda m: m.next_to(moving_target, UP)), run_time=3)
+
+# With alpha (0 to 1) — useful for custom interpolation
+self.play(UpdateFromAlphaFunc(circle, lambda m, a: m.set_fill(opacity=a)), run_time=2)
+```
+
+### turn_animation_into_updater
+
+Convert a one-shot animation into a continuous updater:
+
+```python
+from manim import turn_animation_into_updater
+
+# This would normally play once — now it loops forever
+turn_animation_into_updater(Rotating(gear, rate=PI/4))
+self.add(gear)
+self.wait(5)  # gear rotates for 5 seconds
+```
+
+## Practical patterns
+
+### Pattern 1: Dot tracing a function
+
+```python
+tracker = ValueTracker(0)
+graph = axes.plot(np.sin, x_range=[0, 2*PI], color=PRIMARY)
+dot = always_redraw(lambda: Dot(
+    axes.c2p(tracker.get_value(), np.sin(tracker.get_value())),
+    color=YELLOW
+))
+tangent = always_redraw(lambda: axes.get_secant_slope_group(
+    x=tracker.get_value(), graph=graph, dx=0.01,
+    secant_line_color=HIGHLIGHT, secant_line_length=3
+))
+
+self.add(graph, dot, tangent)
+self.play(tracker.animate.set_value(2*PI), run_time=6, rate_func=linear)
+```
+
+### Pattern 2: Live area under curve
+
+```python
+tracker = ValueTracker(0.5)
+area = always_redraw(lambda: axes.get_area(
+    graph, x_range=[0, tracker.get_value()],
+    color=PRIMARY, opacity=0.3
+))
+area_label = always_redraw(lambda: DecimalNumber(
+    # Numerical integration
+    sum(func(x) * 0.01 for x in np.arange(0, tracker.get_value(), 0.01)),
+    font_size=24
+).next_to(axes, RIGHT))
+
+self.add(area, area_label)
+self.play(tracker.animate.set_value(4), run_time=5)
+```
+
+### Pattern 3: Connected diagram
+
+```python
+# Nodes that can be moved, with edges that auto-follow
+node_a = Dot(LEFT * 2, color=PRIMARY)
+node_b = Dot(RIGHT * 2, color=SECONDARY)
+edge = Line().add_updater(lambda m: m.put_start_and_end_on(
+    node_a.get_center(), node_b.get_center()
+))
+label = Text("edge", font_size=18, font="Menlo").add_updater(
+    lambda m: m.move_to(edge.get_center() + UP * 0.3)
+)
+
+self.add(node_a, node_b, edge, label)
+self.play(node_a.animate.shift(UP * 2), run_time=2)
+self.play(node_b.animate.shift(DOWN + RIGHT), run_time=2)
+# Edge and label follow automatically
+```
+
+### Pattern 4: Parameter exploration
+
+```python
+# Explore how a parameter changes a curve
+a_tracker = ValueTracker(1)
+curve = always_redraw(lambda: axes.plot(
+    lambda x: a_tracker.get_value() * np.sin(x),
+    x_range=[0, 2*PI], color=PRIMARY
+))
+param_label = always_redraw(lambda: Text(
+    f"a = {a_tracker.get_value():.1f}", font_size=24, font="Menlo"
+).to_corner(UR))
+
+self.add(curve, param_label)
+self.play(a_tracker.animate.set_value(3), run_time=3)
+self.play(a_tracker.animate.set_value(0.5), run_time=2)
+self.play(a_tracker.animate.set_value(1), run_time=1)
+```
+
+## Common mistakes
+
+1. **Updater fights animation:** If a mobject has an updater that sets its position, and you try to animate it elsewhere, the updater wins every frame. Suspend updating first.
+
+2. **always_redraw for simple moves:** If you only need to reposition, use `add_updater`. `always_redraw` reconstructs the entire mobject every frame — expensive and unnecessary for position tracking.
+
+3. **Forgetting to add to scene:** Updaters only run on mobjects that are in the scene. `always_redraw` creates the mobject but you still need `self.add()`.
+
+4. **Updater creates new mobjects without cleanup:** If your updater creates Text objects every frame, they accumulate. Use `always_redraw` (which handles cleanup) or update properties in-place.

 ## Font Selection
 
-Manim's default `Text()` uses the system's default sans-serif font, which often renders with poor kerning. Always specify a font explicitly.
+**Use monospace fonts for all text.** Manim's Pango text renderer produces broken kerning with proportional fonts (Helvetica, Inter, SF Pro, Arial) at all sizes and resolutions. Characters overlap and spacing is inconsistent. This is a fundamental Pango limitation, not a Manim bug.
+
+Monospace fonts have fixed character widths — zero kerning issues by design.
 
 ### Recommended Fonts
 
 | Use case | Font | Fallback |
 |----------|------|----------|
-| Body text, titles | `"Inter"`, `"SF Pro Display"` | `"Helvetica Neue"`, `"Arial"` |
-| Code, terminal | `"JetBrains Mono"`, `"SF Mono"` | `"Menlo"`, `"Courier New"` |
-| Math labels | Use `MathTex` (renders via LaTeX, not system fonts) | — |
+| **All text (default)** | `"Menlo"` | `"Courier New"`, `"DejaVu Sans Mono"` |
+| Code, labels | `"JetBrains Mono"`, `"SF Mono"` | `"Menlo"` |
+| Math | Use `MathTex` (renders via LaTeX, not Pango) | — |
 
 ```python
-# Clean body text
-title = Text("Gradient Descent", font_size=48, font="Inter", weight=BOLD)
+MONO = "Menlo"  # define once at top of file
 
-# Monospaced code
-code_label = Text("loss.backward()", font_size=24, font="JetBrains Mono")
+title = Text("Fourier Series", font_size=48, color=PRIMARY, weight=BOLD, font=MONO)
+label = Text("n=1: (4/pi) sin(x)", font_size=20, color=BLUE, font=MONO)
+note = Text("Convergence at discontinuities", font_size=18, color=DIM, font=MONO)
 
 # Math — always use MathTex, not Text
 equation = MathTex(r"\nabla L = \frac{\partial L}{\partial w}")
 ```
 
+### When Proportional Fonts Are Acceptable
+
+Large title text (font_size >= 48) with short strings (1-3 words) can use proportional fonts without visible kerning issues. For anything else — labels, descriptions, multi-word text, small sizes — use monospace.
+
 ### Font Availability
 
-Not all fonts are installed on all systems. Manim falls back silently to a default if the font is missing. Use widely available fonts:
-- **macOS**: SF Pro Display, SF Mono, Menlo, Helvetica Neue
-- **Linux**: DejaVu Sans, Liberation Sans, Ubuntu, Noto Sans
-- **Cross-platform**: Inter (install via Google Fonts), JetBrains Mono (install from jetbrains.com)
+- **macOS**: Menlo (pre-installed), SF Mono
+- **Linux**: DejaVu Sans Mono (pre-installed), Liberation Mono
+- **Cross-platform**: JetBrains Mono (install from jetbrains.com)
 
-For maximum portability, use `"Helvetica Neue"` (body) and `"Menlo"` (code) — both available on macOS and have Linux equivalents.
+`"Menlo"` is the safest default — pre-installed on macOS, and Linux systems fall back to DejaVu Sans Mono.

-### Text Rendering Quality
+### Minimum Font Size
 
-Manim's text rendering quality depends heavily on output resolution. At `-ql` (480p), text kerning looks noticeably poor. Always preview text-heavy scenes at `-qm` (720p) or higher. See `references/rendering.md` for quality preset guidance.
+`font_size=18` is the minimum for readable text at any resolution. Below 18, characters become blurry at `-ql` and barely readable even at `-qh`.

+
+Production pipeline for interactive and generative visual art using [p5.js](https://p5js.org/).
+
+## What it does
+
+Creates browser-based visual art from text prompts. The agent handles the full pipeline: creative concept, code generation, preview, export, and iterative refinement. Output is a single self-contained HTML file that runs in any browser — no build step, no server, no dependencies beyond a CDN script tag.
+
+The output is real interactive art. Not tutorial exercises. Generative systems, particle physics, noise fields, shader effects, kinetic typography — composed with intentional color palettes, layered composition, and visual hierarchy.
+
+## Modes
+
+| Mode | Input | Output |
+|------|-------|--------|
+| **Generative art** | Seed / parameters | Procedural visual composition |
+| **Data visualization** | Dataset / API | Interactive charts, custom data displays |
+| **Interactive experience** | None (user drives) | Mouse/keyboard/touch-driven sketch |
+| **Animation / motion graphics** | Timeline / storyboard | Timed sequences, kinetic typography |
+| **3D scene** | Concept description | WebGL geometry, lighting, shaders |
+| **Image processing** | Image file(s) | Pixel manipulation, filters, pointillism |
+| **Audio-reactive** | Audio file / mic | Sound-driven generative visuals |
+
+## Export Formats
+
+| Format | Method |
+|--------|--------|
+| **HTML** | Self-contained file, opens in any browser |
+| **PNG** | `saveCanvas()` — press 's' to capture |
+| **GIF** | `saveGif()` — press 'g' to capture |
+| **MP4** | Frame sequence + ffmpeg via `scripts/render.sh` |
+| **SVG** | p5.js-svg renderer for vector output |
+
+## Prerequisites
+
+A modern browser. That's it for basic use.
+
+For headless export: Node.js, Puppeteer, ffmpeg.

+# p5.js Production Pipeline
+
+## Creative Standard
+
+This is visual art rendered in the browser. The canvas is the medium; the algorithm is the brush.
+
+**Before writing a single line of code**, articulate the creative concept. What does this piece communicate? What makes the viewer stop scrolling? What separates this from a code tutorial example? The user's prompt is a starting point — interpret it with creative ambition.
+
+**First-render excellence is non-negotiable.** The output must be visually striking on first load. If it looks like a p5.js tutorial exercise, a default configuration, or "AI-generated creative coding," it is wrong. Rethink before shipping.
+
+**Go beyond the reference vocabulary.** The noise functions, particle systems, color palettes, and shader effects in the references are a starting vocabulary. For every project, combine, layer, and invent. The catalog is a palette of paints — you write the painting.
+
+**Be proactively creative.** If the user asks for "a particle system," deliver a particle system with emergent flocking behavior, trailing ghost echoes, palette-shifted depth fog, and a background noise field that breathes. Include at least one visual detail the user didn't ask for but will appreciate.
+
+**Dense, layered, considered.** Every frame should reward viewing. Never flat white backgrounds. Always compositional hierarchy. Always intentional color. Always micro-detail that only appears on close inspection.
+
+**Cohesive aesthetic over feature count.** All elements must serve a unified visual language — shared color temperature, consistent stroke weight vocabulary, harmonious motion speeds. A sketch with ten unrelated effects is worse than one with three that belong together.
+

+| 3D | p5.js WebGL mode | 3D geometry, camera, lighting, GLSL shaders |
+| Audio | p5.sound.js (CDN) | FFT analysis, amplitude, mic input, oscillators |
+| Export | Built-in `saveCanvas()` / `saveGif()` / `saveFrames()` | PNG, GIF, frame sequence output |
+| Capture | CCapture.js (optional) | Deterministic framerate video capture (WebM, GIF) |
+| Headless | Puppeteer + Node.js (optional) | Automated high-res rendering, MP4 via ffmpeg |
+| SVG | p5.js-svg 1.6.0 (optional) | Vector output for print — requires p5.js 1.x |
+| Natural media | p5.brush (optional) | Watercolor, charcoal, pen — requires p5.js 2.x + WEBGL |
+| Texture | p5.grain (optional) | Film grain, texture overlays |
+| Fonts | Google Fonts / `loadFont()` | Custom typography via OTF/TTF/WOFF2 |
+
+### Version Note
+
+**p5.js 1.x** (1.11.3) is the default — stable, well-documented, broadest library compatibility. Use this unless a project requires 2.x features.
+
+**p5.js 2.x** (2.2+) adds: `async setup()` replacing `preload()`, OKLCH/OKLAB color modes, `splineVertex()`, shader `.modify()` API, variable fonts, `textToContours()`, pointer events. Required for p5.brush. See `references/core-api.md` § p5.js 2.0.
+
+## Pipeline
+
+Every project follows the same 6-stage path:
+
+```
+CONCEPT → DESIGN → CODE → PREVIEW → EXPORT → VERIFY
+```
+
+1. **CONCEPT** — Articulate the creative vision: mood, color world, motion vocabulary, what makes this unique
+2. **DESIGN** — Choose mode, canvas size, interaction model, color system, export format. Map concept to technical decisions
+3. **CODE** — Write single HTML file with inline p5.js. Structure: globals → `preload()` → `setup()` → `draw()` → helpers → classes → event handlers
+4. **PREVIEW** — Open in browser, verify visual quality. Test at target resolution. Check performance
+5. **EXPORT** — Capture output: `saveCanvas()` for PNG, `saveGif()` for GIF, `saveFrames()` + ffmpeg for MP4, Puppeteer for headless batch
+6. **VERIFY** — Does the output match the concept? Is it visually striking at the intended display size? Would you frame it?

+
+### Per-Project Variation Rules
+
+Never use default configurations. For every project:
+- **Custom color palette** — never raw `fill(255, 0, 0)`. Always a designed palette with 3-7 colors
+- **Custom stroke weight vocabulary** — thin accents (0.5), medium structure (1-2), bold emphasis (3-5)
+- **Background treatment** — never plain `background(0)` or `background(255)`. Always textured, gradient, or layered
+- **Motion variety** — different speeds for different elements. Primary at 1x, secondary at 0.3x, ambient at 0.1x
+- **At least one invented element** — a custom particle behavior, a novel noise application, a unique interaction response
+
+### Project-Specific Invention
+
+For every project, invent at least one of:
+- A custom color palette matching the mood (not a preset)
+- A novel noise field combination (e.g., curl noise + domain warp + feedback)
+- A unique particle behavior (custom forces, custom trails, custom spawning)
+- An interaction mechanic the user didn't request but that elevates the piece
+- A compositional technique that creates visual hierarchy
+
+### Parameter Design Philosophy
+
+Parameters should emerge from the algorithm, not from a generic menu. Ask: "What properties of *this* system should be tunable?"
+
+**Good parameters** expose the algorithm's character:
+- **Quantities** — how many particles, branches, cells (controls density)
+- **Scales** — noise frequency, element size, spacing (controls texture)
+- **Rates** — speed, growth rate, decay (controls energy)
+- **Thresholds** — when does behavior change? (controls drama)
+- **Ratios** — proportions, balance between forces (controls harmony)
+
+**Bad parameters** are generic controls unrelated to the algorithm:
+- "color1", "color2", "size" — meaningless without context
+- Toggle switches for unrelated effects
+- Parameters that only change cosmetics, not behavior
+
+Every parameter should change how the algorithm *thinks*, not just how it *looks*. A "turbulence" parameter that changes noise octaves is good. A "particle size" slider that only changes `ellipse()` radius is shallow.
+
+## Workflow
+
+### Step 1: Creative Vision
+
+Before any code, articulate:
+
+- **Mood / atmosphere**: What should the viewer feel? Contemplative? Energized? Unsettled? Playful?
+- **Visual story**: What happens over time (or on interaction)? Build? Decay? Transform? Oscillate?
+- **Color world**: Warm/cool? Monochrome? Complementary? What's the dominant hue? The accent?
+- **Shape language**: Organic curves? Sharp geometry? Dots? Lines? Mixed?
+- **Motion vocabulary**: Slow drift? Explosive burst? Breathing pulse? Mechanical precision?
+- **What makes THIS different**: What is the one thing that makes this sketch unique?
+
+Map the user's prompt to aesthetic choices. "Relaxing generative background" demands different everything from "glitch data visualization."
+
+### Step 2: Technical Design
+
+- **Mode** — which of the 7 modes from the table above
+- **Canvas size** — landscape 1920x1080, portrait 1080x1920, square 1080x1080, or responsive `windowWidth/windowHeight`
+- **Renderer** — `P2D` (default) or `WEBGL` (for 3D, shaders, advanced blend modes)
+- **Frame rate** — 60fps (interactive), 30fps (ambient animation), or `noLoop()` (static generative)
+- **Export target** — browser display, PNG still, GIF loop, MP4 video, SVG vector
+- **Interaction model** — passive (no input), mouse-driven, keyboard-driven, audio-reactive, scroll-driven
+- **Viewer UI** — for interactive generative art, start from `templates/viewer.html` which provides seed navigation, parameter sliders, and download. For simple sketches or video export, use bare HTML
+
+### Step 3: Code the Sketch
+
+For **interactive generative art** (seed exploration, parameter tuning): start from `templates/viewer.html`. Read the template first, keep the fixed sections (seed nav, actions), replace the algorithm and parameter controls. This gives the user seed prev/next/random/jump, parameter sliders with live update, and PNG download — all wired up.
+
+For **animations, video export, or simple sketches**: use bare HTML:
+
+Single HTML file. Structure:
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+<head>
+  <meta charset="UTF-8">
+  <meta name="viewport" content="width=device-width, initial-scale=1.0">

+<body>
+<script>
+// === Configuration ===
+const CONFIG = {
+  seed: 42,
+  // ... project-specific params
+};
+
+// === Color Palette ===
+const PALETTE = {
+  bg: '#0a0a0f',
+  primary: '#e8d5b7',
+  // ...
+};
+
+// === Global State ===
+let particles = [];
+
+// === Preload (fonts, images, data) ===
+function preload() {
+  // font = loadFont('...');
+}
+
+// === Setup ===
+function setup() {
+  createCanvas(1920, 1080);
+  randomSeed(CONFIG.seed);
+  noiseSeed(CONFIG.seed);
+  colorMode(HSB, 360, 100, 100, 100);
+  // Initialize state...
+}

+function mousePressed() { /* ... */ }
+function keyPressed() { /* ... */ }
+function windowResized() { resizeCanvas(windowWidth, windowHeight); }
+</script>
+</body>
+</html>
+```
+
+Key implementation patterns:
+- **Seeded randomness**: Always `randomSeed()` + `noiseSeed()` for reproducibility
+- **Color mode**: Use `colorMode(HSB, 360, 100, 100, 100)` for intuitive color control
+- **State separation**: CONFIG for parameters, PALETTE for colors, globals for mutable state
+- **Class-based entities**: Particles, agents, shapes as classes with `update()` + `display()` methods
+- **Offscreen buffers**: `createGraphics()` for layered composition, trails, masks
+
+### Step 4: Preview & Iterate
+
+- Open HTML file directly in browser — no server needed for basic sketches
+- For `loadImage()`/`loadFont()` from local files: use `scripts/serve.sh` or `python3 -m http.server`
+- Chrome DevTools Performance tab to verify 60fps
+- Test at target export resolution, not just the window size
+- Adjust parameters until the visual matches the concept from Step 1
+
+### Step 5: Export
+
+| Format | Method | Command |
+|--------|--------|---------|
+| **PNG** | `saveCanvas('output', 'png')` in `keyPressed()` | Press 's' to save |
+| **High-res PNG** | Puppeteer headless capture | `node scripts/export-frames.js sketch.html --width 3840 --height 2160 --frames 1` |
+| **GIF** | `saveGif('output', 5)` — captures N seconds | Press 'g' to save |
+| **Frame sequence** | `saveFrames('frame', 'png', 10, 30)` — 10s at 30fps | Then `ffmpeg -i frame-%04d.png -c:v libx264 output.mp4` |
+| **MP4** | Puppeteer frame capture + ffmpeg | `bash scripts/render.sh sketch.html output.mp4 --duration 30 --fps 30` |
+| **SVG** | `createCanvas(w, h, SVG)` with p5.js-svg | `save('output.svg')` |
+
+### Step 6: Quality Verification
+
+- **Does it match the vision?** Compare output to the creative concept. If it looks generic, go back to Step 1
+- **Resolution check**: Is it sharp at the target display size? No aliasing artifacts?
+- **Performance check**: Does it hold 60fps in browser? (30fps minimum for animations)
+- **Color check**: Do the colors work together? Test on both light and dark monitors
+- **Edge cases**: What happens at canvas edges? On resize? After running for 10 minutes?
+
+## Critical Implementation Notes
+
+### Performance — Disable FES First
+
+The Friendly Error System (FES) adds up to 10x overhead. Disable it in every production sketch:
+
+```javascript
+p5.disableFriendlyErrors = true;  // BEFORE setup()
+
+function setup() {
+  pixelDensity(1);  // prevent 2x-4x overdraw on retina
+  createCanvas(1920, 1080);
+}
+```
+
+In hot loops (particles, pixel ops), use `Math.*` instead of p5 wrappers — measurably faster:
+
+```javascript
+// In draw() or update() hot paths:
+let a = Math.sin(t);          // not sin(t)
+let r = Math.sqrt(dx*dx+dy*dy); // not dist() — or better: skip sqrt, compare magSq
+let v = Math.random();        // not random() — when seed not needed
+let m = Math.min(a, b);       // not min(a, b)
+```
+
+Never `console.log()` inside `draw()`. Never manipulate DOM in `draw()`. See `references/troubleshooting.md` § Performance.
+
+### Seeded Randomness — Always
+
+Every generative sketch must be reproducible. Same seed, same output.
+
+```javascript
+function setup() {
+  randomSeed(CONFIG.seed);
+  noiseSeed(CONFIG.seed);
+  // All random() and noise() calls now deterministic
+}
+```
+
+Never use `Math.random()` for generative content — only for performance-critical non-visual code. Always `random()` for visual elements. If you need a random seed: `CONFIG.seed = floor(random(99999))`.
+
+### Generative Art Platform Support (fxhash / Art Blocks)
+
+For generative art platforms, replace p5's PRNG with the platform's deterministic random:
+
+```javascript
+// fxhash convention
+const SEED = $fx.hash;              // unique per mint
+const rng = $fx.rand;               // deterministic PRNG
+$fx.features({ palette: 'warm', complexity: 'high' });
+
+// In setup():
+randomSeed(SEED);   // for p5's noise()
+noiseSeed(SEED);
+
+// Replace random() with rng() for platform determinism
+let x = rng() * width;  // instead of random(width)
+```
+
+See `references/export-pipeline.md` § Platform Export.
+
+### Color Mode — Use HSB
+
+HSB (Hue, Saturation, Brightness) is dramatically easier to work with than RGB for generative art:
+
+```javascript
+colorMode(HSB, 360, 100, 100, 100);
+// Now: fill(hue, sat, bri, alpha)
+// Rotate hue: fill((baseHue + offset) % 360, 80, 90)
+// Desaturate: fill(hue, sat * 0.3, bri)
+// Darken: fill(hue, sat, bri * 0.5)
+```
+
+Never hardcode raw RGB values. Define a palette object, derive variations procedurally. See `references/color-systems.md`.
+
+### Noise — Multi-Octave, Not Raw
+
+Raw `noise(x, y)` looks like smooth blobs. Layer octaves for natural texture:
+
+```javascript
+function fbm(x, y, octaves = 4) {
+  let val = 0, amp = 1, freq = 1, sum = 0;
+  for (let i = 0; i < octaves; i++) {
+    val += noise(x * freq, y * freq) * amp;
+    sum += amp;
+    amp *= 0.5;
+    freq *= 2;
+  }
+  return val / sum;
+}
+```
+
+For flowing organic forms, use **domain warping**: feed noise output back as noise input coordinates. See `references/visual-effects.md`.
+
+### createGraphics() for Layers — Not Optional
+
+Flat single-pass rendering looks flat. Use offscreen buffers for composition:
+
+```javascript
+let bgLayer, fgLayer, trailLayer;
+function setup() {
+  createCanvas(1920, 1080);
+  bgLayer = createGraphics(width, height);
+  fgLayer = createGraphics(width, height);
+  trailLayer = createGraphics(width, height);
+}
+function draw() {
+  renderBackground(bgLayer);
+  renderTrails(trailLayer);   // persistent, fading
+  renderForeground(fgLayer);  // cleared each frame
+  image(bgLayer, 0, 0);
+  image(trailLayer, 0, 0);
+  image(fgLayer, 0, 0);
+}
+```
+
+### Performance — Vectorize Where Possible
+
+p5.js draw calls are expensive. For thousands of particles:
+
+```javascript
+// SLOW: individual shapes
+for (let p of particles) {
+  ellipse(p.x, p.y, p.size);
+}
+
+// FAST: single shape with beginShape()
+beginShape(POINTS);
+for (let p of particles) {
+  vertex(p.x, p.y);
+}
+endShape();
+
+// FASTEST: pixel buffer for massive counts
+loadPixels();
+for (let p of particles) {
+  let idx = 4 * (floor(p.y) * width + floor(p.x));
+  pixels[idx] = r; pixels[idx+1] = g; pixels[idx+2] = b; pixels[idx+3] = 255;
+}
+updatePixels();
+```
+
+See `references/troubleshooting.md` § Performance.
+
+### Instance Mode for Multiple Sketches
+
+Global mode pollutes `window`. For production, use instance mode:
+
+```javascript
+const sketch = (p) => {
+  p.setup = function() {
+    p.createCanvas(800, 800);
+  };
+  p.draw = function() {
+    p.background(0);
+    p.ellipse(p.mouseX, p.mouseY, 50);
+  };
+};
+new p5(sketch, 'canvas-container');
+```
+
+Required when embedding multiple sketches on one page or integrating with frameworks.
+
+### WebGL Mode Gotchas
+
+- `createCanvas(w, h, WEBGL)` — origin is center, not top-left
+- Y-axis is inverted (positive Y goes up in WEBGL, down in P2D)
+- `translate(-width/2, -height/2)` to get P2D-like coordinates
+- `push()`/`pop()` around every transform — matrix stack overflows silently
+- `texture()` before `rect()`/`plane()` — not after
+- Custom shaders: `createShader(vert, frag)` — test on multiple browsers
+
+### Export — Key Bindings Convention
+
+Every sketch should include these in `keyPressed()`:
+
+```javascript
+function keyPressed() {
+  if (key === 's' || key === 'S') saveCanvas('output', 'png');
+  if (key === 'g' || key === 'G') saveGif('output', 5);
+  if (key === 'r' || key === 'R') { randomSeed(millis()); noiseSeed(millis()); }
+  if (key === ' ') CONFIG.paused = !CONFIG.paused;
+}
+```
+
+### Headless Video Export — Use noLoop()
+
+For headless rendering via Puppeteer, the sketch **must** use `noLoop()` in setup. Without it, p5's draw loop runs freely while screenshots are slow — the sketch races ahead and you get skipped/duplicate frames.
+
+```javascript
+function setup() {
+  createCanvas(1920, 1080);
+  pixelDensity(1);
+  noLoop();                    // capture script controls frame advance
+  window._p5Ready = true;      // signal readiness to capture script
+}
+```
+
+The bundled `scripts/export-frames.js` detects `_p5Ready` and calls `redraw()` once per capture for exact 1:1 frame correspondence. See `references/export-pipeline.md` § Deterministic Capture.
+
+For multi-scene videos, use the per-clip architecture: one HTML per scene, render independently, stitch with `ffmpeg -f concat`. See `references/export-pipeline.md` § Per-Clip Architecture.
+
+### Agent Workflow
+
+When building p5.js sketches:
+
+1. **Write the HTML file** — single self-contained file, all code inline
+2. **Open in browser** — `open sketch.html` (macOS) or `xdg-open sketch.html` (Linux)
+3. **Local assets** (fonts, images) require a server: `python3 -m http.server 8080` in the project directory, then open `http://localhost:8080/sketch.html`
+4. **Export PNG/GIF** — add `keyPressed()` shortcuts as shown above, tell the user which key to press
+5. **Headless export** — `node scripts/export-frames.js sketch.html --frames 300` for automated frame capture (sketch must use `noLoop()` + `_p5Ready`)
+6. **MP4 rendering** — `bash scripts/render.sh sketch.html output.mp4 --duration 30`
+7. **Iterative refinement** — edit the HTML file, user refreshes browser to see changes
+8. **Load references on demand** — use `skill_view(name="p5js", file_path="references/...")` to load specific reference files as needed during implementation
+

+# Animation
+
+## Frame-Based Animation
+
+### The Draw Loop
+
+```javascript
+function draw() {
+  // Called ~60 times/sec by default
+  // frameCount — integer, starts at 1
+  // deltaTime — ms since last frame (use for framerate-independent motion)
+  // millis() — ms since sketch start
+}
+```
+
+### Time-Based vs Frame-Based
+
+```javascript
+// Frame-based (speed varies with framerate)
+x += speed;
+
+// Time-based (consistent speed regardless of framerate)
+x += speed * (deltaTime / 16.67);  // normalized to 60fps
+```
+
+### Normalized Time
+
+```javascript
+// Progress from 0 to 1 over N seconds
+let duration = 5000;  // 5 seconds in ms
+let t = constrain(millis() / duration, 0, 1);
+
+// Looping progress (0 → 1 → 0 → 1...)
+let period = 3000;  // 3 second loop
+let t = (millis() % period) / period;
+
+// Ping-pong (0 → 1 → 0 → 1...)
+let raw = (millis() % (period * 2)) / period;
+let t = raw <= 1 ? raw : 2 - raw;
+```
+
+## Easing Functions
+
+### Built-in Lerp
+
+```javascript
+// Linear interpolation — smooth but mechanical
+let x = lerp(startX, endX, t);
+
+// Map for non-0-1 ranges
+let y = map(t, 0, 1, startY, endY);
+```
+
+### Common Easing Curves
+
+```javascript
+// Ease in (slow start)
+function easeInQuad(t) { return t * t; }
+function easeInCubic(t) { return t * t * t; }
+function easeInExpo(t) { return t === 0 ? 0 : pow(2, 10 * (t - 1)); }
+
+// Ease out (slow end)
+function easeOutQuad(t) { return 1 - (1 - t) * (1 - t); }
+function easeOutCubic(t) { return 1 - pow(1 - t, 3); }
+function easeOutExpo(t) { return t === 1 ? 1 : 1 - pow(2, -10 * t); }
+
+// Ease in-out (slow both ends)
+function easeInOutCubic(t) {
+  return t < 0.5 ? 4 * t * t * t : 1 - pow(-2 * t + 2, 3) / 2;
+}
+function easeInOutQuint(t) {
+  return t < 0.5 ? 16 * t * t * t * t * t : 1 - pow(-2 * t + 2, 5) / 2;
+}
+
+// Elastic (spring overshoot)
+function easeOutElastic(t) {
+  if (t === 0 || t === 1) return t;
+  return pow(2, -10 * t) * sin((t * 10 - 0.75) * (2 * PI / 3)) + 1;
+}
+
+// Bounce
+function easeOutBounce(t) {
+  if (t < 1/2.75) return 7.5625 * t * t;
+  else if (t < 2/2.75) { t -= 1.5/2.75; return 7.5625 * t * t + 0.75; }
+  else if (t < 2.5/2.75) { t -= 2.25/2.75; return 7.5625 * t * t + 0.9375; }
+  else { t -= 2.625/2.75; return 7.5625 * t * t + 0.984375; }
+}
+
+// Smooth step (Hermite interpolation — great default)
+function smoothstep(t) { return t * t * (3 - 2 * t); }
+
+// Smoother step (Ken Perlin)
+function smootherstep(t) { return t * t * t * (t * (t * 6 - 15) + 10); }
+```
+
+### Applying Easing
+
+```javascript
+// Animate from startVal to endVal over duration ms
+function easedValue(startVal, endVal, startTime, duration, easeFn) {
+  let t = constrain((millis() - startTime) / duration, 0, 1);
+  return lerp(startVal, endVal, easeFn(t));
+}
+
+// Usage
+let x = easedValue(100, 700, animStartTime, 2000, easeOutCubic);
+```
+
+## Spring Physics
+
+More natural than easing — responds to force, overshoots, settles.
+
+```javascript
+class Spring {
+  constructor(value, target, stiffness = 0.1, damping = 0.7) {
+    this.value = value;

+  isSettled(threshold = 0.01) {
+    return abs(this.velocity) < threshold && abs(this.value - this.target) < threshold;

+
+// Usage

+```
+
+### 2D Spring
+
+```javascript
+class Spring2D {
+  constructor(x, y) {
+    this.pos = createVector(x, y);
+    this.target = createVector(x, y);

+    this.vel.add(force).mult(this.damping);
+    this.pos.add(this.vel);
+    return this.pos;
+  }
+}
+```
+
+## State Machines
+
+For complex multi-phase animations.
+
+```javascript
+const STATES = { IDLE: 0, ENTER: 1, ACTIVE: 2, EXIT: 3 };
+let state = STATES.IDLE;
+let stateStart = 0;
+
+function setState(newState) {
+  state = newState;
+  stateStart = millis();
+}
+
+function stateTime() {
+  return millis() - stateStart;
+}
+
+function draw() {
+  switch (state) {
+    case STATES.IDLE:
+      // waiting...
+      break;
+    case STATES.ENTER:
+      let t = constrain(stateTime() / 1000, 0, 1);
+      let alpha = easeOutCubic(t) * 255;
+      // fade in...
+      if (t >= 1) setState(STATES.ACTIVE);
+      break;
+    case STATES.ACTIVE:
+      // main animation...
+      break;
+    case STATES.EXIT:
+      let t2 = constrain(stateTime() / 500, 0, 1);
+      // fade out...
+      if (t2 >= 1) setState(STATES.IDLE);
+      break;
+  }
+}
+```
+
+## Timeline Sequencing
+
+For timed multi-scene animations (motion graphics, title sequences).
+
+```javascript
+class Timeline {
+  constructor() {
+    this.events = [];
+  }
+
+  at(timeMs, duration, fn) {
+    this.events.push({ start: timeMs, end: timeMs + duration, fn });
+    return this;
+  }
+
+  update() {
+    let now = millis();
+    for (let e of this.events) {
+      if (now >= e.start && now < e.end) {
+        let t = (now - e.start) / (e.end - e.start);
+        e.fn(t);
+      }
+    }
+  }
+}
+
+// Usage
+let timeline = new Timeline();
+timeline
+  .at(0, 2000, (t) => {
+    // Scene 1: title fade in (0-2s)
+    let alpha = easeOutCubic(t) * 255;
+    fill(255, alpha);
+    textSize(48);
+    text("Hello", width/2, height/2);
+  })
+  .at(2000, 1000, (t) => {
+    // Scene 2: title fade out (2-3s)
+    let alpha = (1 - easeInCubic(t)) * 255;
+    fill(255, alpha);
+    textSize(48);
+    text("Hello", width/2, height/2);
+  })
+  .at(3000, 5000, (t) => {
+    // Scene 3: main content (3-8s)
+    renderMainContent(t);
+  });
+
+function draw() {
+  background(0);
+  timeline.update();
+}
+```
+
+## Noise-Driven Motion
+
+More organic than deterministic animation.
+
+```javascript
+// Smooth wandering position
+let x = map(noise(frameCount * 0.005, 0), 0, 1, 0, width);
+let y = map(noise(0, frameCount * 0.005), 0, 1, 0, height);
+
+// Noise-driven rotation
+let angle = noise(frameCount * 0.01) * TWO_PI;
+
+// Noise-driven scale (breathing effect)
+let s = map(noise(frameCount * 0.02), 0, 1, 0.8, 1.2);
+
+// Noise-driven color shift
+let hue = map(noise(frameCount * 0.003), 0, 1, 0, 360);
+```
+
+## Transition Patterns
+
+### Fade In/Out
+
+```javascript
+function fadeIn(t) { return constrain(t, 0, 1); }
+function fadeOut(t) { return constrain(1 - t, 0, 1); }
+```
+
+### Slide
+
+```javascript
+function slideIn(t, direction = 'left') {
+  let et = easeOutCubic(t);
+  switch (direction) {
+    case 'left': return lerp(-width, 0, et);
+    case 'right': return lerp(width, 0, et);
+    case 'up': return lerp(-height, 0, et);
+    case 'down': return lerp(height, 0, et);
+  }
+}
+```
+
+### Scale Reveal
+
+```javascript
+function scaleReveal(t) {
+  let et = easeOutElastic(constrain(t, 0, 1));
+  push();
+  translate(width/2, height/2);
+  scale(et);
+  translate(-width/2, -height/2);
+  // draw content...
+  pop();
+}
+```
+
+### Staggered Entry
+
+```javascript
+// N elements appear one after another
+let staggerDelay = 100;  // ms between each
+for (let i = 0; i < elements.length; i++) {
+  let itemStart = baseTime + i * staggerDelay;
+  let t = constrain((millis() - itemStart) / 500, 0, 1);
+  let alpha = easeOutCubic(t) * 255;
+  let yOffset = lerp(30, 0, easeOutCubic(t));
+  // draw element with alpha and yOffset
+}
+```
+
+## Recording Deterministic Animations
+
+For frame-perfect export, use frame count instead of millis():
+
+```javascript
+const TOTAL_FRAMES = 300;  // 10 seconds at 30fps
+const FPS = 30;
+
+function draw() {
+  let t = frameCount / TOTAL_FRAMES;  // 0 to 1 over full duration
+  if (t > 1) { noLoop(); return; }
+
+  // Use t for all animation timing — deterministic
+  renderFrame(t);
+
+  // Export
+  if (CONFIG.recording) {
+    saveCanvas('frame-' + nf(frameCount, 4), 'png');
+  }
+}
+```
+
+## Scene Fade Envelopes (Video)
+
+Every scene in a multi-scene video needs fade-in and fade-out. Hard cuts between visually different generative scenes are jarring.
+
+```javascript
+const SCENE_FRAMES = 150;  // 5 seconds at 30fps
+const FADE = 15;           // half-second fade
+
+function draw() {
+  let lf = frameCount - 1;  // 0-indexed local frame
+  let t = lf / SCENE_FRAMES; // 0..1 normalized progress
+
+  // Fade envelope: ramp up at start, ramp down at end
+  let fade = 1;
+  if (lf < FADE) fade = lf / FADE;
+  if (lf > SCENE_FRAMES - FADE) fade = (SCENE_FRAMES - lf) / FADE;
+  fade = fade * fade * (3 - 2 * fade);  // smoothstep for organic feel
+
+  // Apply fade to all visual output
+  // Option 1: multiply alpha values by fade
+  fill(r, g, b, alpha * fade);
+
+  // Option 2: tint entire composited image
+  tint(255, fade * 255);
+  image(sceneBuffer, 0, 0);
+  noTint();
+
+  // Option 3: multiply pixel brightness (for pixel-level scenes)
+  pixels[i] = r * fade;
+}
+```
+
+## Animating Static Algorithms
+
+Some generative algorithms produce a single static result (attractors, circle packing, Voronoi). In video, static content reads as frozen/broken. Techniques to add motion:
+
+### Progressive Reveal
+
+Expand a mask from center outward to reveal the precomputed result:
+
+```javascript
+let revealRadius = easeOutCubic(min(t * 1.5, 1)) * (width * 0.8);
+// In the render loop, skip pixels beyond revealRadius from center
+let dx = x - width/2, dy = y - height/2;
+if (sqrt(dx*dx + dy*dy) > revealRadius) continue;
+// Soft edge:
+let edgeFade = constrain((revealRadius - dist) / 40, 0, 1);
+```
+
+### Parameter Sweep
+
+Slowly change a parameter to show the algorithm evolving:
+
+```javascript
+// Attractor with drifting parameters
+let a = -1.7 + sin(t * 0.5) * 0.2;  // oscillate around base value
+let b = 1.3 + cos(t * 0.3) * 0.15;
+```
+
+### Slow Camera Motion
+
+Apply subtle zoom or rotation to the final image:
+
+```javascript
+push();
+translate(width/2, height/2);
+scale(1 + t * 0.05);       // slow 5% zoom over scene duration
+rotate(t * 0.1);            // gentle rotation
+translate(-width/2, -height/2);
+image(precomputedResult, 0, 0);
+pop();
+```
+
+### Overlay Dynamic Elements
+
+Add particles, grain, or subtle noise on top of static content:
+
+```javascript
+// Static background
+image(staticResult, 0, 0);
+// Dynamic overlay
+for (let p of ambientParticles) {
+  p.update();
+  p.display();  // slow-moving specks add life
+}
+```

+# Color Systems
+
+## Color Modes
+
+### HSB (Recommended for Generative Art)
+
+```javascript
+colorMode(HSB, 360, 100, 100, 100);
+// Hue: 0-360 (color wheel position)
+// Saturation: 0-100 (gray to vivid)
+// Brightness: 0-100 (black to full)
+// Alpha: 0-100
+
+fill(200, 80, 90);        // blue, vivid, bright
+fill(200, 80, 90, 50);    // 50% transparent
+```
+
+HSB advantages:
+- Rotate hue: `(baseHue + offset) % 360`
+- Desaturate: reduce S
+- Darken: reduce B
+- Monochrome variations: fix H, vary S and B
+- Complementary: `(hue + 180) % 360`
+- Analogous: `hue +/- 30`
+
+### HSL
+
+```javascript
+colorMode(HSL, 360, 100, 100, 100);
+// Lightness 50 = pure color, 0 = black, 100 = white
+// More intuitive for tints (L > 50) and shades (L < 50)
+```
+
+### RGB
+
+```javascript
+colorMode(RGB, 255, 255, 255, 255);  // default
+// Direct channel control, less intuitive for procedural palettes
+```
+
+## Color Objects
+
+```javascript
+let c = color(200, 80, 90);    // create color object
+fill(c);
+
+// Extract components
+let h = hue(c);
+let s = saturation(c);
+let b = brightness(c);
+let r = red(c);
+let g = green(c);
+let bl = blue(c);
+let a = alpha(c);
+
+// Hex colors work everywhere
+fill('#e8d5b7');
+fill('#e8d5b7cc');  // with alpha
+
+// Modify via setters
+c.setAlpha(128);
+c.setRed(200);
+```
+
+## Color Interpolation
+
+### lerpColor
+
+```javascript
+let c1 = color(0, 80, 100);    // red
+let c2 = color(200, 80, 100);  // blue
+let mixed = lerpColor(c1, c2, 0.5);  // midpoint blend
+// Works in current colorMode
+```
+
+### paletteLerp (p5.js 1.11+)
+
+Interpolate through multiple colors at once.
+
+```javascript
+let colors = [
+  color('#2E0854'),
+  color('#850E35'),
+  color('#EE6C4D'),
+  color('#F5E663')
+];
+let c = paletteLerp(colors, t);  // t = 0..1, interpolates through all
+```
+
+### Manual Multi-Stop Gradient
+
+```javascript
+function multiLerp(colors, t) {
+  t = constrain(t, 0, 1);
+  let segment = t * (colors.length - 1);
+  let idx = floor(segment);
+  let frac = segment - idx;
+  idx = min(idx, colors.length - 2);
+  return lerpColor(colors[idx], colors[idx + 1], frac);
+}
+```
+
+## Gradient Rendering
+
+### Linear Gradient
+
+```javascript
+function linearGradient(x1, y1, x2, y2, c1, c2) {
+  let steps = dist(x1, y1, x2, y2);
+  for (let i = 0; i <= steps; i++) {
+    let t = i / steps;
+    let c = lerpColor(c1, c2, t);
+    stroke(c);
+    let x = lerp(x1, x2, t);
+    let y = lerp(y1, y2, t);
+    // Draw perpendicular line at each point
+    let dx = -(y2 - y1) / steps * 1000;
+    let dy = (x2 - x1) / steps * 1000;
+    line(x - dx, y - dy, x + dx, y + dy);
+  }
+}
+```
+
+### Radial Gradient
+
+```javascript
+function radialGradient(cx, cy, r, innerColor, outerColor) {
+  noStroke();
+  for (let i = r; i > 0; i--) {
+    let t = 1 - i / r;
+    fill(lerpColor(innerColor, outerColor, t));
+    ellipse(cx, cy, i * 2);
+  }
+}
+```
+
+### Noise-Based Gradient
+
+```javascript
+function noiseGradient(colors, noiseScale, time) {
+  loadPixels();
+  for (let y = 0; y < height; y++) {
+    for (let x = 0; x < width; x++) {
+      let n = noise(x * noiseScale, y * noiseScale, time);
+      let c = multiLerp(colors, n);
+      let idx = 4 * (y * width + x);
+      pixels[idx] = red(c);
+      pixels[idx+1] = green(c);
+      pixels[idx+2] = blue(c);
+      pixels[idx+3] = 255;
+    }
+  }
+  updatePixels();
+}
+```
+
+## Procedural Palette Generation
+

+function complementary(baseHue) {
+  return [baseHue, (baseHue + 180) % 360];
+}
+```

+    (baseHue - spread + 360) % 360,
+    baseHue,
+    (baseHue + spread) % 360
+  ];
+}
+```
+
+### Triadic
+
+```javascript
+function triadic(baseHue) {
+  return [baseHue, (baseHue + 120) % 360, (baseHue + 240) % 360];

+
+### Split Complementary
+
+```javascript
+function splitComplementary(baseHue) {
+  return [baseHue, (baseHue + 150) % 360, (baseHue + 210) % 360];
+}
+```
+
+### Tetradic (Rectangle)
+
+```javascript
+function tetradic(baseHue) {
+  return [baseHue, (baseHue + 60) % 360, (baseHue + 180) % 360, (baseHue + 240) % 360];
+}
+```
+
+### Monochromatic Variations
+
+```javascript
+function monoVariations(hue, count = 5) {
+  let colors = [];
+  for (let i = 0; i < count; i++) {
+    let s = map(i, 0, count - 1, 20, 90);
+    let b = map(i, 0, count - 1, 95, 40);
+    colors.push(color(hue, s, b));

+## Background Techniques
+
+### Textured Background
+
+```javascript
+function texturedBackground(baseColor, noiseScale, noiseAmount) {
+  loadPixels();
+  let r = red(baseColor), g = green(baseColor), b = blue(baseColor);
+  for (let i = 0; i < pixels.length; i += 4) {

+    pixels[i+1] = constrain(g + n, 0, 255);
+    pixels[i+2] = constrain(b + n, 0, 255);
+    pixels[i+3] = 255;
+  }
+  updatePixels();
+}
+```
+
+### Vignette
+
+```javascript
+function vignette(strength = 0.5, radius = 0.7) {
+  loadPixels();
+  let cx = width / 2, cy = height / 2;
+  let maxDist = dist(0, 0, cx, cy);

+// ALWAYS call before createCanvas()
+function setup() {
+  pixelDensity(1);        // first
+  createCanvas(1920, 1080); // second
+}
+```
+
+For export, always `pixelDensity(1)` and use the exact target resolution. Never rely on device scaling for final output.
+
+### Responsive Resize
+
+```javascript
+function windowResized() {
+  resizeCanvas(windowWidth, windowHeight);
+  // Recreate offscreen buffers at new size
+  bgLayer = createGraphics(width, height);
+  // Reinitialize any size-dependent state
+}
+```
+
+## Coordinate System
+
+### P2D (Default)
+- Origin: top-left (0, 0)
+- X increases rightward
+- Y increases downward
+- Angles: radians by default, `angleMode(DEGREES)` to switch
+
+### WEBGL
+- Origin: center of canvas
+- X increases rightward, Y increases **upward**, Z increases toward viewer
+- To get P2D-like coordinates in WEBGL: `translate(-width/2, -height/2)`
+
+## Draw Loop
+
+```javascript
+function preload() {
+  // Load assets before setup — fonts, images, JSON, CSV
+  // Blocks execution until all loads complete
+  font = loadFont('font.otf');
+  img = loadImage('texture.png');
+  data = loadJSON('data.json');
+}
+
+function setup() {
+  // Runs once. Create canvas, initialize state.
+  createCanvas(1920, 1080);
+  colorMode(HSB, 360, 100, 100, 100);
+  randomSeed(CONFIG.seed);
+  noiseSeed(CONFIG.seed);
+}
+
+function draw() {
+  // Runs every frame (default 60fps).
+  // Set frameRate(30) in setup() to change.
+  // Call noLoop() for static sketches (render once).
+}
+```
+
+### Frame Control
+
+```javascript
+frameRate(30);           // set target FPS
+noLoop();                // stop draw loop (static pieces)
+loop();                  // restart draw loop
+redraw();                // call draw() once (manual refresh)
+frameCount              // frames since start (integer)
+deltaTime               // milliseconds since last frame (float)
+millis()                // milliseconds since sketch started
+```
+
+## Transform Stack
+
+Every transform is cumulative. Use `push()`/`pop()` to isolate.
+
+```javascript
+push();
+  translate(width / 2, height / 2);
+  rotate(angle);
+  scale(1.5);
+  // draw something at transformed position
+  ellipse(0, 0, 100, 100);
+pop();
+// back to original coordinate system
+```
+
+### Transform Functions
+
+| Function | Effect |
+|----------|--------|
+| `translate(x, y)` | Move origin |
+| `rotate(angle)` | Rotate around origin (radians) |
+| `scale(s)` / `scale(sx, sy)` | Scale from origin |
+| `shearX(angle)` | Skew X axis |
+| `shearY(angle)` | Skew Y axis |
+| `applyMatrix(a, b, c, d, e, f)` | Arbitrary 2D affine transform |
+| `resetMatrix()` | Clear all transforms |
+
+### Composition Pattern: Rotate Around Center
+
+```javascript
+push();
+  translate(cx, cy);       // move origin to center
+  rotate(angle);           // rotate around that center
+  translate(-cx, -cy);     // move origin back
+  // draw at original coordinates, but rotated around (cx, cy)
+  rect(cx - 50, cy - 50, 100, 100);
+pop();
+```
+
+## Offscreen Buffers (createGraphics)
+
+Offscreen buffers are separate canvases you can draw to and composite. Essential for:
+- **Layered composition** — background, midground, foreground
+- **Persistent trails** — draw to buffer, fade with semi-transparent rect, never clear
+- **Masking** — draw mask to buffer, apply with `image()` or pixel operations
+- **Post-processing** — render scene to buffer, apply effects, draw to main canvas
+
+```javascript
+let layer;
+
+function setup() {
+  createCanvas(1920, 1080);
+  layer = createGraphics(width, height);
+}
+
+function draw() {
+  // Draw to offscreen buffer
+  layer.background(0, 10);  // semi-transparent clear = trails
+  layer.fill(255);
+  layer.ellipse(mouseX, mouseY, 20);
+
+  // Composite to main canvas
+  image(layer, 0, 0);
+}
+```
+
+### Trail Effect Pattern
+
+```javascript
+let trailBuffer;
+
+function setup() {
+  createCanvas(1920, 1080);
+  trailBuffer = createGraphics(width, height);
+  trailBuffer.background(0);
+}
+
+function draw() {
+  // Fade previous frame (lower alpha = longer trails)
+  trailBuffer.noStroke();
+  trailBuffer.fill(0, 0, 0, 15);  // RGBA — 15/255 alpha
+  trailBuffer.rect(0, 0, width, height);
+
+  // Draw new content
+  trailBuffer.fill(255);
+  trailBuffer.ellipse(mouseX, mouseY, 10);
+
+  // Show
+  image(trailBuffer, 0, 0);
+}
+```
+
+### Multi-Layer Composition
+
+```javascript
+let bgLayer, contentLayer, fxLayer;
+
+function setup() {
+  createCanvas(1920, 1080);
+  bgLayer = createGraphics(width, height);
+  contentLayer = createGraphics(width, height);
+  fxLayer = createGraphics(width, height);
+}
+
+function draw() {
+  // Background — drawn once or slowly evolving
+  renderBackground(bgLayer);
+
+  // Content — main visual elements
+  contentLayer.clear();
+  renderContent(contentLayer);
+
+  // FX — overlays, vignettes, grain
+  fxLayer.clear();
+  renderEffects(fxLayer);
+
+  // Composite with blend modes
+  image(bgLayer, 0, 0);
+  blendMode(ADD);
+  image(contentLayer, 0, 0);
+  blendMode(MULTIPLY);
+  image(fxLayer, 0, 0);
+  blendMode(BLEND);  // reset
+}
+```
+
+## Composition Patterns
+
+### Grid Layout
+
+```javascript
+let cols = 10, rows = 10;
+let cellW = width / cols;
+let cellH = height / rows;
+for (let i = 0; i < cols; i++) {
+  for (let j = 0; j < rows; j++) {
+    let cx = cellW * (i + 0.5);
+    let cy = cellH * (j + 0.5);
+    // draw element at (cx, cy) within cell size (cellW, cellH)
+  }
+}
+```
+
+### Radial Layout
+
+```javascript
+let n = 12;
+for (let i = 0; i < n; i++) {
+  let angle = TWO_PI * i / n;
+  let r = 300;
+  let x = width/2 + cos(angle) * r;
+  let y = height/2 + sin(angle) * r;
+  // draw element at (x, y)
+}
+```
+
+### Golden Ratio Spiral
+
+```javascript
+let phi = (1 + sqrt(5)) / 2;
+let n = 500;
+for (let i = 0; i < n; i++) {
+  let angle = i * TWO_PI / (phi * phi);
+  let r = sqrt(i) * 10;
+  let x = width/2 + cos(angle) * r;
+  let y = height/2 + sin(angle) * r;
+  let size = map(i, 0, n, 8, 2);
+  ellipse(x, y, size);
+}
+```
+
+### Margin-Aware Composition
+
+```javascript
+const MARGIN = 80;  // pixels from edge
+const drawW = width - 2 * MARGIN;
+const drawH = height - 2 * MARGIN;
+
+// Map normalized [0,1] coordinates to drawable area
+function mapX(t) { return MARGIN + t * drawW; }
+function mapY(t) { return MARGIN + t * drawH; }
+```
+
+## Random and Noise
+
+### Seeded Random
+
+```javascript
+randomSeed(42);
+let x = random(100);        // always same value for seed 42
+let y = random(-1, 1);      // range
+let item = random(myArray);  // random element
+```
+
+### Gaussian Random
+
+```javascript
+let x = randomGaussian(0, 1);  // mean=0, stddev=1
+// Useful for natural-looking distributions
+```
+
+### Perlin Noise
+
+```javascript
+noiseSeed(42);
+noiseDetail(4, 0.5);  // 4 octaves, 0.5 falloff
+
+let v = noise(x * 0.01, y * 0.01);  // returns 0.0 to 1.0
+// Scale factor (0.01) controls feature size — smaller = smoother
+```
+
+## Math Utilities
+
+| Function | Description |

+| `lerp(a, b, t)` | Linear interpolation |
+| `norm(v, lo, hi)` | Normalize to 0-1 |

+| `fract(n)` | Fractional part |
+
+## p5.js 2.0 Changes
+
+p5.js 2.0 (released Apr 2025, current: 2.2) introduces breaking changes. The p5.js editor defaults to 1.x until Aug 2026. Use 2.x only when you need its features.
+
+### async setup() replaces preload()
+
+```javascript
+// p5.js 1.x
+let img;
+function preload() { img = loadImage('cat.jpg'); }
+function setup() { createCanvas(800, 800); }
+
+// p5.js 2.x
+let img;
+async function setup() {
+  createCanvas(800, 800);
+  img = await loadImage('cat.jpg');
+}
+```
+
+### New Color Modes
+
+```javascript
+colorMode(OKLCH);  // perceptually uniform — better gradients
+// L: 0-1 (lightness), C: 0-0.4 (chroma), H: 0-360 (hue)
+fill(0.7, 0.15, 200);  // medium-bright saturated blue
+
+colorMode(OKLAB);  // perceptually uniform, no hue angle
+colorMode(HWB);    // Hue-Whiteness-Blackness
+```
+
+### splineVertex() replaces curveVertex()
+
+No more doubling first/last control points:
+
+```javascript
+// p5.js 1.x — must repeat first and last
+beginShape();
+curveVertex(pts[0].x, pts[0].y);  // doubled
+for (let p of pts) curveVertex(p.x, p.y);
+curveVertex(pts[pts.length-1].x, pts[pts.length-1].y);  // doubled
+endShape();
+
+// p5.js 2.x — clean
+beginShape();
+for (let p of pts) splineVertex(p.x, p.y);
+endShape();
+```
+
+### Shader .modify() API
+
+Modify built-in shaders without writing full GLSL:
+
+```javascript
+let myShader = baseMaterialShader().modify({
+  vertexDeclarations: 'uniform float uTime;',
+  'vec4 getWorldPosition': `(vec4 pos) {
+    pos.y += sin(pos.x * 0.1 + uTime) * 20.0;
+    return pos;
+  }`
+});
+```
+
+### Variable Fonts
+
+```javascript
+textWeight(700);  // dynamic weight without loading multiple files
+```
+
+### textToContours() and textToModel()
+
+```javascript
+let contours = font.textToContours('HELLO', 0, 0, 200);
+// Returns array of contour arrays (closed paths)
+
+let geo = font.textToModel('HELLO', 0, 0, 200);
+// Returns p5.Geometry for 3D extruded text
+```

+# Export Pipeline
+
+## PNG Export
+
+### In-Sketch (Keyboard Shortcut)
+
+```javascript
+function keyPressed() {
+  if (key === 's' || key === 'S') {
+    saveCanvas('output', 'png');
+    // Downloads output.png immediately
+  }
+}
+```
+
+### Timed Export (Static Generative)
+
+```javascript
+function setup() {
+  createCanvas(3840, 2160);
+  pixelDensity(1);
+  randomSeed(CONFIG.seed);
+  noiseSeed(CONFIG.seed);
+  noLoop();
+}
+
+function draw() {
+  // ... render everything ...
+  saveCanvas('output-seed-' + CONFIG.seed, 'png');
+}
+```
+
+### High-Resolution Export
+
+For resolutions beyond screen size, use `pixelDensity()` or a large offscreen buffer:
+
+```javascript
+function exportHighRes(scale) {
+  let buffer = createGraphics(width * scale, height * scale);
+  buffer.scale(scale);
+  // Re-render everything to buffer at higher resolution
+  renderScene(buffer);
+  buffer.save('highres-output.png');
+}
+```
+
+### Batch Seed Export
+
+```javascript
+function exportBatch(startSeed, count) {
+  for (let i = 0; i < count; i++) {
+    CONFIG.seed = startSeed + i;
+    randomSeed(CONFIG.seed);
+    noiseSeed(CONFIG.seed);
+    // Render
+    background(0);
+    renderScene();
+    saveCanvas('seed-' + nf(CONFIG.seed, 5), 'png');
+  }
+}
+```
+
+## GIF Export
+
+### saveGif()
+
+```javascript
+function keyPressed() {
+  if (key === 'g' || key === 'G') {
+    saveGif('output', 5);
+    // Captures 5 seconds of animation
+    // Options: saveGif(filename, duration, options)
+  }
+}
+
+// With options
+saveGif('output', 5, {
+  delay: 0,        // delay before starting capture (seconds)
+  units: 'seconds' // or 'frames'
+});
+```
+
+Limitations:
+- GIF is 256 colors max — dithering artifacts on gradients
+- Large canvases produce huge files
+- Use a smaller canvas (640x360) for GIF, higher for PNG/MP4
+- Frame rate is approximate
+
+### Optimal GIF Settings
+
+```javascript
+// For GIF output, use smaller canvas and lower framerate
+function setup() {
+  createCanvas(640, 360);
+  frameRate(15);  // GIF standard
+  pixelDensity(1);
+}
+```
+
+## Frame Sequence Export
+
+### saveFrames()
+
+```javascript
+function keyPressed() {
+  if (key === 'f') {
+    saveFrames('frame', 'png', 10, 30);
+    // 10 seconds, 30 fps → 300 PNG files
+    // Downloads as individual files (browser may block bulk downloads)
+  }
+}
+```
+
+### Manual Frame Export (More Control)
+
+```javascript
+let recording = false;
+let frameNum = 0;
+const TOTAL_FRAMES = 300;
+
+function keyPressed() {
+  if (key === 'r') recording = !recording;
+}
+
+function draw() {
+  // ... render frame ...
+
+  if (recording) {
+    saveCanvas('frame-' + nf(frameNum, 4), 'png');
+    frameNum++;
+    if (frameNum >= TOTAL_FRAMES) {
+      recording = false;
+      noLoop();
+      console.log('Recording complete: ' + frameNum + ' frames');
+    }
+  }
+}
+```
+
+### Deterministic Capture (Critical for Video)
+
+The `noLoop()` + `redraw()` pattern is **required** for frame-perfect headless capture. Without it, p5's draw loop runs freely in Chrome while Puppeteer screenshots are slow — the sketch runs ahead and you get duplicate/missing frames.
+
+```javascript
+function setup() {
+  createCanvas(1920, 1080);
+  pixelDensity(1);
+  noLoop();                    // STOP the automatic draw loop
+  window._p5Ready = true;      // Signal to capture script
+}
+
+function draw() {
+  // This only runs when redraw() is called by the capture script
+  // frameCount increments exactly once per redraw()
+}
+```
+
+The bundled `scripts/export-frames.js` detects `window._p5Ready` and switches to deterministic mode automatically. Without it, falls back to timed capture (less precise).
+
+### ffmpeg: Frames to MP4
+
+```bash
+# Basic encoding
+ffmpeg -framerate 30 -i frame-%04d.png -c:v libx264 -pix_fmt yuv420p output.mp4
+
+# High quality
+ffmpeg -framerate 30 -i frame-%04d.png \
+  -c:v libx264 -preset slow -crf 18 -pix_fmt yuv420p \
+  output.mp4
+
+# With audio
+ffmpeg -framerate 30 -i frame-%04d.png -i audio.mp3 \
+  -c:v libx264 -c:a aac -shortest \
+  output.mp4
+
+# Loop for social media (3 loops)
+ffmpeg -stream_loop 2 -i output.mp4 -c copy output-looped.mp4
+```
+
+### Video Export Gotchas
+
+**YUV420 clips dark values.** H.264 encodes in YUV420 color space, which rounds dark RGB values. Content below RGB(8,8,8) may become pure black. Subtle dark details (dim particle trails, faint noise textures) disappear in the encoded video even though they're visible in the PNG frames.
+
+**Fix:** Ensure minimum brightness of ~10 for any visible content. Test by encoding a few frames and comparing the MP4 frame vs the source PNG.
+
+```bash
+# Extract a frame from MP4 for comparison
+ffmpeg -i output.mp4 -vf "select=eq(n\,100)" -vframes 1 check.png
+```
+
+**Static frames look broken in video.** If an algorithm produces a single static image (like a pre-computed attractor heatmap), it reads as a freeze/glitch in video. Always add animation even to static content:
+- Progressive reveal (expand from center, sweep across)
+- Slow parameter drift (rotate color mapping, shift noise offset)
+- Camera-like motion (slow zoom, slight pan)
+- Overlay animated particles or grain
+
+**Scene transitions are mandatory.** Hard cuts between visually different scenes are jarring. Use fade envelopes:
+
+```javascript
+const FADE_FRAMES = 15;  // half-second at 30fps
+let fade = 1;
+if (localFrame < FADE_FRAMES) fade = localFrame / FADE_FRAMES;
+if (localFrame > SCENE_FRAMES - FADE_FRAMES) fade = (SCENE_FRAMES - localFrame) / FADE_FRAMES;
+fade = fade * fade * (3 - 2 * fade);  // smoothstep
+// Apply: multiply all alpha/brightness by fade
+```
+
+### Per-Clip Architecture (Multi-Scene Videos)
+
+For videos with multiple scenes, render each as a separate HTML file + MP4 clip, then stitch with ffmpeg. This enables re-rendering individual scenes without touching the rest.
+
+**Directory structure:**
+```
+project/
+├── capture-scene.js          # Shared: node capture-scene.js <html> <outdir> <frames>
+├── render-all.sh             # Renders all + stitches
+├── scenes/
+│   ├── 00-intro.html         # Each scene is self-contained
+│   ├── 01-particles.html
+│   ├── 02-noise.html
+│   └── 03-outro.html
+└── clips/
+    ├── 00-intro.mp4          # Each clip rendered independently
+    ├── 01-particles.mp4
+    ├── 02-noise.mp4
+    ├── 03-outro.mp4
+    └── concat.txt
+```
+
+**Stitch clips with ffmpeg concat:**
+```bash
+# concat.txt (order determines final sequence)
+file '00-intro.mp4'
+file '01-particles.mp4'
+file '02-noise.mp4'
+file '03-outro.mp4'
+
+# Lossless stitch (all clips must have same codec/resolution/fps)
+ffmpeg -f concat -safe 0 -i concat.txt -c copy final.mp4
+```
+
+**Re-render a single scene:**
+```bash
+node capture-scene.js scenes/01-particles.html clips/01-particles 150
+ffmpeg -y -framerate 30 -i clips/01-particles/frame-%04d.png \
+  -c:v libx264 -preset slow -crf 16 -pix_fmt yuv420p clips/01-particles.mp4
+# Then re-stitch
+ffmpeg -y -f concat -safe 0 -i clips/concat.txt -c copy final.mp4
+```
+
+**Re-order without re-rendering:** Just change the order in concat.txt and re-stitch. No frames need re-rendering.
+
+**Each scene HTML must:**
+- Call `noLoop()` in setup and set `window._p5Ready = true`
+- Use `frameCount`-based timing (not `millis()`) for deterministic output
+- Handle its own fade-in/fade-out envelope
+- Be fully self-contained (no shared state between scenes)
+
+### ffmpeg: Frames to GIF (Better Quality)
+
+```bash
+# Generate palette first for optimal colors
+ffmpeg -i frame-%04d.png -vf "fps=15,palettegen=max_colors=256" palette.png
+
+# Render GIF using palette
+ffmpeg -i frame-%04d.png -i palette.png \
+  -lavfi "fps=15 [x]; [x][1:v] paletteuse=dither=bayer:bayer_scale=3" \
+  output.gif
+```
+
+## Headless Export (Puppeteer)
+
+For automated, server-side, or CI rendering. Uses a headless Chrome browser to run the sketch.
+
+### export-frames.js (Node.js Script)
+
+See `scripts/export-frames.js` for the full implementation. Basic pattern:
+
+```javascript
+const puppeteer = require('puppeteer');
+
+async function captureFrames(htmlPath, outputDir, options) {
+  const browser = await puppeteer.launch({
+    headless: true,
+    args: ['--no-sandbox', '--disable-setuid-sandbox']
+  });
+  const page = await browser.newPage();
+
+  await page.setViewport({
+    width: options.width || 1920,
+    height: options.height || 1080,
+    deviceScaleFactor: 1
+  });
+
+  await page.goto(`file://${path.resolve(htmlPath)}`, {
+    waitUntil: 'networkidle0'
+  });
+
+  // Wait for sketch to initialize
+  await page.waitForSelector('canvas');
+  await page.waitForTimeout(1000);
+
+  for (let i = 0; i < options.frames; i++) {
+    const canvas = await page.$('canvas');
+    await canvas.screenshot({
+      path: path.join(outputDir, `frame-${String(i).padStart(4, '0')}.png`)
+    });
+
+    // Advance one frame
+    await page.evaluate(() => { redraw(); });
+    await page.waitForTimeout(1000 / options.fps);
+  }
+
+  await browser.close();
+}
+```
+
+### render.sh (Full Pipeline)
+
+See `scripts/render.sh` for the complete render script. Pipeline:
+
+```
+1. Launch Puppeteer → open sketch HTML
+2. Capture N frames as PNG sequence
+3. Pipe to ffmpeg → encode H.264 MP4
+4. Optional: add audio track
+5. Clean up temp frames
+```
+
+## SVG Export
+
+### Using p5.js-svg Library
+
+```html
+<script src="https://unpkg.com/p5.js-svg@1.5.1"></script>
+```
+
+```javascript
+function setup() {
+  createCanvas(1920, 1080, SVG);  // SVG renderer
+  noLoop();
+}
+
+function draw() {
+  // Only vector operations (no pixels, no blend modes)
+  stroke(0);
+  noFill();
+  for (let i = 0; i < 100; i++) {
+    let x = random(width);
+    let y = random(height);
+    ellipse(x, y, random(10, 50));
+  }
+  save('output.svg');
+}
+```
+
+Limitations:
+- No `loadPixels()`, `updatePixels()`, `filter()`, `blendMode()`
+- No WebGL
+- No pixel-level effects
+- Great for: line art, geometric patterns, plots
+
+### Hybrid: Raster Background + SVG Overlay
+
+Render background effects to PNG, then SVG for crisp vector elements on top.
+
+## Export Format Decision Guide
+
+| Need | Format | Method |
+|------|--------|--------|
+| Single still image | PNG | `saveCanvas()` or `keyPressed()` |
+| Print-quality still | PNG (high-res) | `pixelDensity(1)` + large canvas |

+## Tiling for Ultra-High-Resolution
+
+For resolutions too large for a single canvas (e.g., 10000x10000 for print):
+
+```javascript
+function renderTiled(totalW, totalH, tileSize) {
+  let cols = ceil(totalW / tileSize);
+  let rows = ceil(totalH / tileSize);
+
+  for (let ty = 0; ty < rows; ty++) {
+    for (let tx = 0; tx < cols; tx++) {
+      let buffer = createGraphics(tileSize, tileSize);
+      buffer.push();
+      buffer.translate(-tx * tileSize, -ty * tileSize);
+      renderScene(buffer, totalW, totalH);
+      buffer.pop();
+      buffer.save(`tile-${tx}-${ty}.png`);
+      buffer.remove();  // free memory
+    }
+  }
+  // Stitch with ImageMagick:
+  // montage tile-*.png -tile 4x4 -geometry +0+0 final.png
+}
+```
+
+## CCapture.js — Deterministic Video Capture
+
+The built-in `saveFrames()` has limitations: small frame counts, memory issues, browser download blocking. CCapture.js solves all of these by hooking into the browser's timing functions to simulate constant time steps regardless of actual render speed.
+
+```html
+<script src="https://cdn.jsdelivr.net/npm/ccapture.js-npmfixed/build/CCapture.all.min.js"></script>
+```
+
+### Basic Setup
+
+```javascript
+let capturer;
+let recording = false;
+
+function setup() {
+  createCanvas(1920, 1080);
+  pixelDensity(1);
+
+  capturer = new CCapture({
+    format: 'webm',       // 'webm', 'gif', 'png', 'jpg'
+    framerate: 30,
+    quality: 99,           // 0-100 for webm/jpg
+    // timeLimit: 10,      // auto-stop after N seconds
+    // motionBlurFrames: 4 // supersampled motion blur
+  });
+}
+
+function draw() {
+  // ... render frame ...
+
+  if (recording) {
+    capturer.capture(document.querySelector('canvas'));
+  }
+}
+
+function keyPressed() {
+  if (key === 'c') {
+    if (!recording) {
+      capturer.start();
+      recording = true;
+      console.log('Recording started');
+    } else {
+      capturer.stop();
+      capturer.save();  // triggers download
+      recording = false;
+      console.log('Recording saved');
+    }
+  }
+}
+```
+
+### Format Comparison
+
+| Format | Quality | Size | Browser Support |
+|--------|---------|------|-----------------|
+| **WebM** | High | Medium | Chrome only |
+| **GIF** | 256 colors | Large | All (via gif.js worker) |
+| **PNG sequence** | Lossless | Very large (TAR) | All |
+| **JPEG sequence** | Lossy | Large (TAR) | All |
+
+### Important: Timing Hook
+
+CCapture.js overrides `Date.now()`, `setTimeout`, `requestAnimationFrame`, and `performance.now()`. This means:
+- `millis()` returns simulated time (perfect for recording)
+- `deltaTime` is constant (1000/framerate)
+- Complex sketches that take 500ms per frame still record at smooth 30fps
+- **Caveat**: Audio sync breaks (audio plays in real-time, not simulated time)
+
+## Programmatic Export (canvas API)
+
+For custom export workflows beyond `saveCanvas()`:
+
+```javascript
+// Canvas to Blob (for upload, processing)
+document.querySelector('canvas').toBlob((blob) => {
+  // Upload to server, process, etc.
+  let url = URL.createObjectURL(blob);
+  console.log('Blob URL:', url);
+}, 'image/png');
+
+// Canvas to Data URL (for inline embedding)
+let dataUrl = document.querySelector('canvas').toDataURL('image/png');
+// Use in <img src="..."> or send as base64
+```
+
+## SVG Export (p5.js-svg)
+
+```html
+<script src="https://unpkg.com/p5.js-svg@1.6.0"></script>
+```
+
+```javascript
+function setup() {
+  createCanvas(1920, 1080, SVG);  // SVG renderer
+  noLoop();
+}
+
+function draw() {
+  // Only vector operations work (no pixel ops, no blendMode)
+  stroke(0);
+  noFill();
+  for (let i = 0; i < 100; i++) {
+    ellipse(random(width), random(height), random(10, 50));
+  }
+  save('output.svg');
+}
+```
+
+**Critical SVG caveats:**
+- **Must call `clear()` in `draw()`** for animated sketches — SVG DOM accumulates child elements, causing memory bloat
+- `blendMode()` is **not implemented** in SVG renderer
+- `filter()`, `loadPixels()`, `updatePixels()` don't work
+- Requires **p5.js 1.11.x** — not compatible with p5.js 2.x
+- Perfect for: line art, geometric patterns, pen plotter output
+
+## Platform Export
+
+### fxhash Conventions
+
+```javascript
+// Replace p5's random with fxhash's deterministic PRNG
+const rng = $fx.rand;
+
+// Declare features for rarity/filtering
+$fx.features({
+  'Palette': paletteName,
+  'Complexity': complexity > 0.7 ? 'High' : 'Low',
+  'Has Particles': particleCount > 0
+});
+
+// Declare on-chain parameters

+
+```javascript
+// Platform provides a hash string
+const hash = tokenData.hash;  // Art Blocks convention
+
+// Build deterministic PRNG from hash

+## Mouse Events
+
+### Continuous State
+
+```javascript
+mouseX, mouseY          // current position (relative to canvas)
+pmouseX, pmouseY        // previous frame position
+mouseIsPressed          // boolean

+movedX, movedY          // delta since last frame
+winMouseX, winMouseY    // relative to window (not canvas)
+```
+
+### Event Callbacks
+
+```javascript
+function mousePressed() {
+  // fires once on press
+  // mouseButton tells you which button
+}
+
+function mouseReleased() {
+  // fires once on release
+}
+
+function mouseClicked() {
+  // fires after press+release (same element)
+}
+
+function doubleClicked() {
+  // fires on double-click
+}
+
+function mouseMoved() {
+  // fires when mouse moves (no button pressed)
+}
+
+function mouseDragged() {
+  // fires when mouse moves WITH button pressed

+function mouseWheel(event) {
+  // event.delta: positive = scroll down, negative = scroll up
+  zoom += event.delta * -0.01;
+  return false;  // prevent page scroll
+}
+```
+
+### Mouse Interaction Patterns
+
+**Spawn on click:**
+```javascript
+function mousePressed() {
+  particles.push(new Particle(mouseX, mouseY));
+}
+```
+
+**Mouse follow with spring:**
+```javascript
+let springX, springY;
+function setup() {
+  springX = new Spring(width/2, width/2);
+  springY = new Spring(height/2, height/2);
+}
+function draw() {
+  springX.setTarget(mouseX);
+  springY.setTarget(mouseY);
+  let x = springX.update();
+  let y = springY.update();
+  ellipse(x, y, 50);
+}
+```
+
+**Drag interaction:**
+```javascript
+let dragging = false;
+let dragObj = null;
+let offsetX, offsetY;
+
+function mousePressed() {
+  for (let obj of objects) {
+    if (dist(mouseX, mouseY, obj.x, obj.y) < obj.radius) {
+      dragging = true;
+      dragObj = obj;
+      offsetX = mouseX - obj.x;
+      offsetY = mouseY - obj.y;
+      break;
+    }
+  }
+}
+
+function mouseDragged() {
+  if (dragging && dragObj) {
+    dragObj.x = mouseX - offsetX;
+    dragObj.y = mouseY - offsetY;
+  }
+}
+
+function mouseReleased() {
+  dragging = false;
+  dragObj = null;
+}
+```
+
+**Mouse repulsion (particles flee cursor):**
+```javascript
+function draw() {
+  let mousePos = createVector(mouseX, mouseY);
+  for (let p of particles) {
+    let d = p.pos.dist(mousePos);
+    if (d < 150) {
+      let repel = p5.Vector.sub(p.pos, mousePos);
+      repel.normalize();
+      repel.mult(map(d, 0, 150, 5, 0));
+      p.applyForce(repel);
+    }
+  }
+}
+```
+
+## Keyboard Events

+```
+
+### Event Callbacks

+
+function keyReleased() {
+  // fires once on release
+}
+
+function keyTyped() {
+  // fires for printable characters only (not arrows, shift, etc.)

+```javascript
+beginShape();
+  vertex(100, 100);
+  vertex(200, 50);
+  vertex(300, 100);
+  vertex(250, 200);

+
+## Bezier Curves
+
+### Cubic Bezier
+
+```javascript
+bezier(x1, y1, cx1, cy1, cx2, cy2, x2, y2);
+// x1,y1 = start point
+// cx1,cy1 = first control point
+// cx2,cy2 = second control point
+// x2,y2 = end point
+```
+
+### Bezier in custom shapes
+
+```javascript
+beginShape();

+  bezierVertex(150, 50, 250, 50, 300, 200);
+  // control1, control2, endpoint
+endShape();
+```
+
+### Quadratic Bezier
+
+```javascript
+beginShape();
+  vertex(100, 200);
+  quadraticVertex(200, 50, 300, 200);
+  // single control point + endpoint
+endShape();
+```
+
+### Interpolation along Bezier
+
+```javascript
+let x = bezierPoint(x1, cx1, cx2, x2, t);  // t = 0..1
+let y = bezierPoint(y1, cy1, cy2, y2, t);
+let tx = bezierTangent(x1, cx1, cx2, x2, t); // tangent
+```
+
+## Catmull-Rom Splines
+
+```javascript
+curve(cpx1, cpy1, x1, y1, x2, y2, cpx2, cpy2);
+// cpx1,cpy1 = control point before start
+// x1,y1 = start point (visible)
+// x2,y2 = end point (visible)
+// cpx2,cpy2 = control point after end
+
+curveVertex(x, y);  // in beginShape() — smooth curve through all points
+curveTightness(0);  // 0 = Catmull-Rom, 1 = straight lines, -1 = loose
+```
+
+### Smooth curve through points
+
+```javascript
+let points = [/* array of {x, y} */];
+beginShape();
+  curveVertex(points[0].x, points[0].y); // repeat first for tangent
+  for (let p of points) {
+    curveVertex(p.x, p.y);
+  }
+  curveVertex(points[points.length-1].x, points[points.length-1].y); // repeat last
+endShape();
+```
+
+## p5.Vector
+
+Essential for physics, particle systems, and geometric computation.
+
+```javascript
+let v = createVector(x, y);
+
+// Arithmetic (modifies in place)
+v.add(other);        // vector addition

+p5.Vector.add(a, b);      // a + b → new vector
+p5.Vector.sub(a, b);      // a - b → new vector
+p5.Vector.fromAngle(a);   // unit vector at angle
+p5.Vector.random2D();     // random unit vector
+p5.Vector.lerp(a, b, t);  // interpolate
+
+// Copy
+let copy = v.copy();
+```
+
+## Signed Distance Fields (2D)
+
+SDFs return the distance from a point to the nearest edge of a shape. Negative inside, positive outside. Useful for smooth shapes, glow effects, boolean operations.
+
+```javascript
+// Circle SDF
+function sdCircle(px, py, cx, cy, r) {
+  return dist(px, py, cx, cy) - r;
+}
+
+// Box SDF
+function sdBox(px, py, cx, cy, hw, hh) {
+  let dx = abs(px - cx) - hw;
+  let dy = abs(py - cy) - hh;
+  return sqrt(max(dx, 0) ** 2 + max(dy, 0) ** 2) + min(max(dx, dy), 0);
+}
+
+// Line segment SDF
+function sdSegment(px, py, ax, ay, bx, by) {
+  let pa = createVector(px - ax, py - ay);
+  let ba = createVector(bx - ax, by - ay);
+  let t = constrain(pa.dot(ba) / ba.dot(ba), 0, 1);
+  let closest = p5.Vector.add(createVector(ax, ay), p5.Vector.mult(ba, t));
+  return dist(px, py, closest.x, closest.y);
+}
+
+// Smooth boolean union
+function opSmoothUnion(d1, d2, k) {
+  let h = constrain(0.5 + 0.5 * (d2 - d1) / k, 0, 1);
+  return lerp(d2, d1, h) - k * h * (1 - h);
+}
+
+// Rendering SDF as glow
+let d = sdCircle(x, y, width/2, height/2, 200);
+let glow = exp(-abs(d) * 0.02);  // exponential falloff
+fill(glow * 255);
+```
+
+## Useful Geometry Patterns
+
+### Regular Polygon
+
+```javascript
+function regularPolygon(cx, cy, r, sides) {
+  beginShape();
+  for (let i = 0; i < sides; i++) {
+    let a = TWO_PI * i / sides - HALF_PI;
+    vertex(cx + cos(a) * r, cy + sin(a) * r);
+  }
+  endShape(CLOSE);
+}
+```
+
+### Star Shape
+
+```javascript
+function star(cx, cy, r1, r2, npoints) {
+  beginShape();
+  let angle = TWO_PI / npoints;
+  let halfAngle = angle / 2;
+  for (let a = -HALF_PI; a < TWO_PI - HALF_PI; a += angle) {
+    vertex(cx + cos(a) * r2, cy + sin(a) * r2);
+    vertex(cx + cos(a + halfAngle) * r1, cy + sin(a + halfAngle) * r1);
+  }
+  endShape(CLOSE);
+}
+```
+
+### Rounded Line (Capsule)
+
+```javascript
+function capsule(x1, y1, x2, y2, weight) {
+  strokeWeight(weight);
+  strokeCap(ROUND);
+  line(x1, y1, x2, y2);
+}
+```
+
+### Soft Body / Blob
+
+```javascript
+function blob(cx, cy, baseR, noiseScale, noiseOffset, detail = 64) {
+  beginShape();
+  for (let i = 0; i < detail; i++) {
+    let a = TWO_PI * i / detail;
+    let r = baseR + noise(cos(a) * noiseScale + noiseOffset,
+                          sin(a) * noiseScale + noiseOffset) * baseR * 0.4;
+    vertex(cx + cos(a) * r, cy + sin(a) * r);
+  }
+  endShape(CLOSE);
+}
+```
+
+## Clipping and Masking
+
+```javascript
+// Clip shape — everything drawn after is masked by the clip shape
+beginClip();
+  circle(width/2, height/2, 400);
+endClip();
+// Only content inside the circle is visible
+image(myImage, 0, 0);
+
+// Or functional form
+clip(() => {
+  circle(width/2, height/2, 400);
+});
+
+// Erase mode — cut holes
+erase();
+  circle(mouseX, mouseY, 100);  // this area becomes transparent
+noErase();
+```

+# Troubleshooting
+
+## Performance
+
+### Step Zero — Disable FES
+
+The Friendly Error System (FES) adds massive overhead — up to 10x slowdown. Disable it in every production sketch:
+
+```javascript
+// BEFORE any p5 code
+p5.disableFriendlyErrors = true;
+
+// Or use p5.min.js instead of p5.js — FES is stripped from minified build
+```
+
+### Step One — pixelDensity(1)
+
+Retina/HiDPI displays default to 2x or 3x density, multiplying pixel count by 4-9x:
+
+```javascript
+function setup() {
+  pixelDensity(1);        // force 1:1 — always do this first
+  createCanvas(1920, 1080);
+}
+```
+
+### Use Math.* in Hot Loops
+
+p5's `sin()`, `cos()`, `random()`, `min()`, `max()`, `abs()` are wrapper functions with overhead. In hot loops (thousands of iterations per frame), use native `Math.*`:
+
+```javascript
+// SLOW — p5 wrappers
+for (let p of particles) {
+  let a = sin(p.angle);
+  let d = dist(p.x, p.y, mx, my);
+}
+
+// FAST — native Math
+for (let p of particles) {
+  let a = Math.sin(p.angle);
+  let dx = p.x - mx, dy = p.y - my;
+  let dSq = dx * dx + dy * dy;  // skip sqrt entirely
+}
+```
+
+Use `magSq()` instead of `mag()` for distance comparisons — avoids expensive `sqrt()`.
+
+### Diagnosis
+
+Open Chrome DevTools > Performance tab > Record while sketch runs.
+
+Common bottlenecks:
+1. **FES enabled** — 10x overhead on every p5 function call
+2. **pixelDensity > 1** — 4x pixel count, 4x slower
+3. **Too many draw calls** — thousands of `ellipse()`, `rect()` per frame
+4. **Large canvas + pixel operations** — `loadPixels()`/`updatePixels()` on 4K canvas
+5. **Unoptimized particle systems** — checking all-vs-all distances (O(n^2))
+6. **Memory leaks** — creating objects every frame without cleanup
+7. **Shader compilation** — calling `createShader()` in `draw()` instead of `setup()`
+8. **console.log() in draw()** — DOM write per frame, destroys performance
+9. **DOM manipulation in draw()** — layout thrashing (400-500x slower than canvas ops)
+
+### Solutions
+
+**Reduce draw calls:**
+```javascript
+// BAD: 10000 individual circles
+for (let p of particles) {
+  ellipse(p.x, p.y, p.size);
+}
+
+// GOOD: single shape with vertices
+beginShape(POINTS);
+for (let p of particles) {
+  vertex(p.x, p.y);
+}
+endShape();
+
+// BEST: direct pixel manipulation
+loadPixels();
+for (let p of particles) {
+  let idx = 4 * (floor(p.y) * width + floor(p.x));
+  pixels[idx] = p.r;
+  pixels[idx+1] = p.g;
+  pixels[idx+2] = p.b;
+  pixels[idx+3] = 255;
+}
+updatePixels();
+```
+
+**Spatial hashing for neighbor queries:**
+```javascript
+class SpatialHash {
+  constructor(cellSize) {
+    this.cellSize = cellSize;
+    this.cells = new Map();
+  }
+
+  clear() { this.cells.clear(); }
+
+  _key(x, y) {
+    return `${floor(x / this.cellSize)},${floor(y / this.cellSize)}`;
+  }
+
+  insert(obj) {
+    let key = this._key(obj.pos.x, obj.pos.y);
+    if (!this.cells.has(key)) this.cells.set(key, []);
+    this.cells.get(key).push(obj);
+  }
+
+  query(x, y, radius) {
+    let results = [];
+    let minCX = floor((x - radius) / this.cellSize);
+    let maxCX = floor((x + radius) / this.cellSize);
+    let minCY = floor((y - radius) / this.cellSize);
+    let maxCY = floor((y + radius) / this.cellSize);
+
+    for (let cx = minCX; cx <= maxCX; cx++) {
+      for (let cy = minCY; cy <= maxCY; cy++) {
+        let key = `${cx},${cy}`;
+        let cell = this.cells.get(key);
+        if (cell) {
+          for (let obj of cell) {
+            if (dist(x, y, obj.pos.x, obj.pos.y) <= radius) {
+              results.push(obj);
+            }
+          }
+        }
+      }
+    }
+    return results;
+  }
+}
+```
+
+**Object pooling:**
+```javascript
+class ParticlePool {
+  constructor(maxSize) {
+    this.pool = [];
+    this.active = [];
+    for (let i = 0; i < maxSize; i++) {
+      this.pool.push(new Particle(0, 0));
+    }
+  }
+
+  spawn(x, y) {
+    let p = this.pool.pop();
+    if (p) {
+      p.reset(x, y);
+      this.active.push(p);
+    }
+  }
+
+  update() {
+    for (let i = this.active.length - 1; i >= 0; i--) {
+      this.active[i].update();
+      if (this.active[i].isDead()) {
+        this.pool.push(this.active.splice(i, 1)[0]);
+      }
+    }
+  }
+}
+```
+
+**Throttle heavy operations:**
+```javascript
+// Only update flow field every N frames
+if (frameCount % 5 === 0) {
+  flowField.update(frameCount * 0.001);
+}
+```
+
+### Frame Rate Targets
+
+| Context | Target | Acceptable |
+|---------|--------|------------|
+| Interactive sketch | 60fps | 30fps |
+| Ambient animation | 30fps | 20fps |
+| Export/recording | 30fps render | Any (offline) |
+| Mobile | 30fps | 20fps |
+
+### Per-Pixel Rendering Budgets
+
+Pixel-level operations (`loadPixels()` loops) are the most expensive common pattern. Budget depends on canvas size and computation per pixel.
+
+| Canvas | Pixels | Simple noise (1 call) | fBM (4 octave) | Domain warp (3-layer fBM) |
+|--------|--------|----------------------|----------------|--------------------------|
+| 540x540 | 291K | ~5ms | ~20ms | ~80ms |
+| 1080x1080 | 1.17M | ~20ms | ~80ms | ~300ms+ |
+| 1920x1080 | 2.07M | ~35ms | ~140ms | ~500ms+ |
+| 3840x2160 | 8.3M | ~140ms | ~560ms | WILL CRASH |
+
+**Rules of thumb:**
+- 1 `noise()` call per pixel at 1080x1080 = ~20ms/frame (OK at 30fps)
+- 4-octave fBM per pixel at 1080x1080 = ~80ms/frame (borderline)
+- Multi-layer domain warp at 1080x1080 = 300ms+ (too slow for real-time, fine for `noLoop()` export)
+- **Headless Chrome is 2-5x slower** than desktop Chrome for pixel ops
+
+**Solution: render at lower resolution, fill blocks:**
+```javascript
+let step = 3;  // render 1/9 of pixels, fill 3x3 blocks
+loadPixels();
+for (let y = 0; y < H; y += step) {
+  for (let x = 0; x < W; x += step) {
+    let v = expensiveNoise(x, y);
+    for (let dy = 0; dy < step && y+dy < H; dy++)
+      for (let dx = 0; dx < step && x+dx < W; dx++) {
+        let i = 4 * ((y+dy) * W + (x+dx));
+        pixels[i] = v; pixels[i+1] = v; pixels[i+2] = v; pixels[i+3] = 255;
+      }
+  }
+}
+updatePixels();
+```
+
+Step=2 gives 4x speedup. Step=3 gives 9x. Visible at 1080p but acceptable for video (motion hides it).
+
+## Common Mistakes
+
+### 1. Forgetting to reset blend mode
+
+```javascript
+blendMode(ADD);
+image(glowLayer, 0, 0);
+// WRONG: everything after this is ADD blended
+blendMode(BLEND);  // ALWAYS reset
+```
+
+### 2. Creating objects in draw()
+
+```javascript
+// BAD: creates new font object every frame
+function draw() {
+  let f = loadFont('font.otf');  // NEVER load in draw()
+}
+
+// GOOD: load in preload, use in draw
+let f;
+function preload() { f = loadFont('font.otf'); }
+```
+
+### 3. Not using push()/pop() with transforms
+
+```javascript
+// BAD: transforms accumulate
+translate(100, 0);
+rotate(0.1);
+ellipse(0, 0, 50);
+// Everything after this is also translated and rotated
+
+// GOOD: isolated transforms
+push();
+translate(100, 0);
+rotate(0.1);
+ellipse(0, 0, 50);
+pop();
+```
+
+### 4. Integer coordinates for crisp lines
+
+```javascript
+// BLURRY: sub-pixel rendering
+line(10.5, 20.3, 100.7, 80.2);
+
+// CRISP: integer + 0.5 for 1px lines
+line(10.5, 20.5, 100.5, 80.5);  // on pixel boundary
+```
+
+### 5. Pixel density confusion
+
+```javascript
+// WRONG: assuming pixel array matches canvas dimensions
+loadPixels();
+let idx = 4 * (y * width + x);  // wrong if pixelDensity > 1
+
+// RIGHT: account for pixel density
+let d = pixelDensity();
+loadPixels();
+let idx = 4 * ((y * d) * (width * d) + (x * d));
+
+// SIMPLEST: set pixelDensity(1) at the start
+```
+
+### 6. Color mode confusion
+
+```javascript
+// In HSB mode, fill(255) is NOT white
+colorMode(HSB, 360, 100, 100);
+fill(255);  // This is hue=255, sat=100, bri=100 = vivid purple
+
+// White in HSB:
+fill(0, 0, 100);  // any hue, 0 saturation, 100 brightness
+
+// Black in HSB:
+fill(0, 0, 0);
+```
+
+### 7. WebGL origin is center
+
+```javascript
+// In WEBGL mode, (0,0) is CENTER, not top-left
+function draw() {
+  // This draws at the center, not the corner
+  rect(0, 0, 100, 100);
+
+  // For top-left behavior:
+  translate(-width/2, -height/2);
+  rect(0, 0, 100, 100);  // now at top-left
+}
+```
+
+### 8. createGraphics cleanup
+
+```javascript
+// BAD: memory leak — buffer never freed
+function draw() {
+  let temp = createGraphics(width, height);  // new buffer every frame!
+  // ...
+}
+
+// GOOD: create once, reuse
+let temp;
+function setup() {
+  temp = createGraphics(width, height);
+}
+function draw() {
+  temp.clear();
+  // ... reuse temp
+}
+
+// If you must create/destroy:
+temp.remove();  // explicitly free
+```
+
+### 9. noise() returns 0-1, not -1 to 1
+
+```javascript
+let n = noise(x);  // 0.0 to 1.0 (biased toward 0.5)
+
+// For -1 to 1 range:
+let n = noise(x) * 2 - 1;
+
+// For a specific range:
+let n = map(noise(x), 0, 1, -100, 100);
+```
+
+### 10. saveCanvas() in draw() saves every frame
+
+```javascript
+// BAD: saves a PNG every single frame
+function draw() {
+  // ... render ...
+  saveCanvas('output', 'png');  // DON'T DO THIS
+}
+
+// GOOD: save once via keyboard
+function keyPressed() {
+  if (key === 's') saveCanvas('output', 'png');
+}
+
+// GOOD: save once after rendering static piece
+function draw() {
+  // ... render ...
+  saveCanvas('output', 'png');
+  noLoop();  // stop after saving
+}
+```
+
+### 11. console.log() in draw()
+
+```javascript
+// BAD: writes to DOM console every frame — massive overhead
+function draw() {
+  console.log(particles.length);  // 60 DOM writes/second
+}
+
+// GOOD: log periodically or conditionally
+function draw() {
+  if (frameCount % 60 === 0) console.log('FPS:', frameRate().toFixed(1));
+}
+```
+
+### 12. DOM manipulation in draw()
+
+```javascript
+// BAD: layout thrashing — 400-500x slower than canvas ops
+function draw() {
+  document.getElementById('counter').innerText = frameCount;
+  let el = document.querySelector('.info');  // DOM query per frame
+}
+
+// GOOD: cache DOM refs, update infrequently
+let counterEl;
+function setup() { counterEl = document.getElementById('counter'); }
+function draw() {
+  if (frameCount % 30 === 0) counterEl.innerText = frameCount;
+}
+```
+
+### 13. Not disabling FES in production
+
+```javascript
+// BAD: every p5 function call has error-checking overhead (up to 10x slower)
+function setup() { createCanvas(800, 800); }
+
+// GOOD: disable before any p5 code
+p5.disableFriendlyErrors = true;
+function setup() { createCanvas(800, 800); }
+
+// ALSO GOOD: use p5.min.js (FES stripped from minified build)
+```
+
+## Browser Compatibility
+
+### Safari Issues
+- WebGL shader precision: always declare `precision mediump float;`
+- `AudioContext` requires user gesture (`userStartAudio()`)
+- Some `blendMode()` options behave differently
+
+### Firefox Issues
+- `textToPoints()` may return slightly different point counts
+- WebGL extensions may differ from Chrome
+- Color profile handling can shift colors
+
+### Mobile Issues
+- Touch events need `return false` to prevent scroll
+- `devicePixelRatio` can be 2x or 3x — use `pixelDensity(1)` for performance
+- Smaller canvas recommended (720p or less)
+- Audio requires explicit user gesture to start
+
+## CORS Issues
+
+```javascript
+// Loading images/fonts from external URLs requires CORS headers
+// Local files need a server:
+// python3 -m http.server 8080
+
+// Or use a CORS proxy for external resources (not recommended for production)
+```
+
+## Memory Leaks
+
+### Symptoms
+- Framerate degrading over time
+- Browser tab memory growing unbounded
+- Page becomes unresponsive after minutes
+
+### Common Causes
+
+```javascript
+// 1. Growing arrays
+let history = [];
+function draw() {
+  history.push(someData);  // grows forever
+}
+// FIX: cap the array
+if (history.length > 1000) history.shift();
+
+// 2. Creating p5 objects in draw()
+function draw() {
+  let v = createVector(0, 0);  // allocation every frame
+}
+// FIX: reuse pre-allocated objects
+
+// 3. Unreleased graphics buffers
+let layers = [];
+function reset() {
+  for (let l of layers) l.remove();  // free old buffers
+  layers = [];
+}
+
+// 4. Event listener accumulation
+function setup() {
+  // BAD: adds new listener every time setup runs
+  window.addEventListener('resize', handler);
+}
+// FIX: use p5's built-in windowResized()
+```
+
+## Debugging Tips
+
+### Console Logging
+
+```javascript
+// Log once (not every frame)
+if (frameCount === 1) {
+  console.log('Canvas:', width, 'x', height);
+  console.log('Pixel density:', pixelDensity());
+  console.log('Renderer:', drawingContext.constructor.name);
+}
+
+// Log periodically
+if (frameCount % 60 === 0) {
+  console.log('FPS:', frameRate().toFixed(1));
+  console.log('Particles:', particles.length);
+}
+```
+
+### Visual Debugging
+
+```javascript
+// Show frame rate
+function draw() {
+  // ... your sketch ...
+  if (CONFIG.debug) {
+    fill(255, 0, 0);
+    noStroke();
+    textSize(14);
+    textAlign(LEFT, TOP);
+    text('FPS: ' + frameRate().toFixed(1), 10, 10);
+    text('Particles: ' + particles.length, 10, 28);
+    text('Frame: ' + frameCount, 10, 46);
+  }
+}
+
+// Toggle debug with 'd' key
+function keyPressed() {
+  if (key === 'd') CONFIG.debug = !CONFIG.debug;
+}
+```
+
+### Isolating Issues
+
+```javascript
+// Comment out layers to find the slow one
+function draw() {
+  renderBackground();      // comment out to test
+  // renderParticles();    // this might be slow
+  // renderPostEffects();  // or this
+}
+```

+# Typography
+
+## Loading Fonts
+
+### System Fonts
+
+```javascript
+textFont('Helvetica');
+textFont('Georgia');
+textFont('monospace');
+```
+
+### Custom Fonts (OTF/TTF/WOFF2)
+
+```javascript
+let myFont;
+
+function preload() {
+  myFont = loadFont('path/to/font.otf');
+  // Requires local server or CORS-enabled URL
+}
+
+function setup() {
+  textFont(myFont);
+}
+```
+
+### Google Fonts via CSS
+
+```html
+<link href="https://fonts.googleapis.com/css2?family=Inter:wght@400;700&display=swap" rel="stylesheet">
+<script>
+function setup() {
+  textFont('Inter');
+}
+</script>
+```
+
+Google Fonts work without `loadFont()` but only for `text()` — not for `textToPoints()`. For particle text, you need `loadFont()` with an OTF/TTF file.
+
+## Text Rendering
+
+### Basic Text
+
+```javascript
+textSize(32);
+textAlign(CENTER, CENTER);
+text('Hello World', width/2, height/2);
+```
+
+### Text Properties
+
+```javascript
+textSize(48);                    // pixel size
+textAlign(LEFT, TOP);            // horizontal: LEFT, CENTER, RIGHT
+                                 // vertical: TOP, CENTER, BOTTOM, BASELINE
+textLeading(40);                 // line spacing (for multi-line text)
+textStyle(BOLD);                 // NORMAL, BOLD, ITALIC, BOLDITALIC
+textWrap(WORD);                  // WORD or CHAR (for text() with max width)
+```
+
+### Text Metrics
+
+```javascript
+let w = textWidth('Hello');      // pixel width of string
+let a = textAscent();            // height above baseline
+let d = textDescent();           // height below baseline
+let totalH = a + d;              // full line height
+```
+
+### Text Bounding Box
+
+```javascript
+let bounds = myFont.textBounds('Hello', x, y, size);
+// bounds = { x, y, w, h }
+// Useful for positioning, collision, background rectangles
+```
+
+### Multi-Line Text
+
+```javascript
+// With max width — auto wraps
+textWrap(WORD);
+text('Long text that wraps within the given width', x, y, maxWidth);
+
+// With max width AND height — clips
+text('Very long text', x, y, maxWidth, maxHeight);
+```
+
+## textToPoints() — Text as Particles
+
+Convert text outline to array of points. Requires a loaded font (OTF/TTF via `loadFont()`).
+
+```javascript
+let font;
+let points;
+
+function preload() {
+  font = loadFont('font.otf');  // MUST be loadFont, not CSS
+}
+

+## Noise
+
+### Perlin Noise Basics
+
+```javascript
+noiseSeed(42);
+noiseDetail(4, 0.5);  // octaves, falloff
+
+// 1D noise — smooth undulation
+let y = noise(x * 0.01);  // returns 0.0 to 1.0
+
+// 2D noise — terrain/texture
+let v = noise(x * 0.005, y * 0.005);
+
+// 3D noise — animated 2D field (z = time)
+let v = noise(x * 0.005, y * 0.005, frameCount * 0.005);
+```
+
+The scale factor (0.005 etc.) is critical:
+- `0.001` — very smooth, large features
+- `0.005` — smooth, medium features
+- `0.01` — standard generative art scale
+- `0.05` — detailed, small features
+- `0.1` — near-random, grainy
+
+### Fractal Brownian Motion (fBM)
+
+Layered noise octaves for natural-looking texture. Each octave adds detail at smaller scale.
+
+```javascript
+function fbm(x, y, octaves = 6, lacunarity = 2.0, gain = 0.5) {
+  let value = 0;
+  let amplitude = 1.0;
+  let frequency = 1.0;
+  let maxValue = 0;
+  for (let i = 0; i < octaves; i++) {
+    value += noise(x * frequency, y * frequency) * amplitude;
+    maxValue += amplitude;
+    amplitude *= gain;
+    frequency *= lacunarity;
+  }
+  return value / maxValue;
+}
+```
+
+### Domain Warping
+
+Feed noise output back as input coordinates for flowing organic distortion.
+
+```javascript
+function domainWarp(x, y, scale, strength, time) {
+  // First warp pass
+  let qx = fbm(x + 0.0, y + 0.0);
+  let qy = fbm(x + 5.2, y + 1.3);
+
+  // Second warp pass (feed back)
+  let rx = fbm(x + strength * qx + 1.7, y + strength * qy + 9.2, 4, 2, 0.5);
+  let ry = fbm(x + strength * qx + 8.3, y + strength * qy + 2.8, 4, 2, 0.5);
+
+  return fbm(x + strength * rx + time, y + strength * ry + time);
+}
+```
+
+### Curl Noise
+
+Divergence-free noise field. Particles following curl noise never converge or diverge — they flow in smooth, swirling patterns.
+
+```javascript
+function curlNoise(x, y, scale, time) {
+  let eps = 0.001;
+  // Partial derivatives via finite differences
+  let dndx = (noise(x * scale + eps, y * scale, time) -
+              noise(x * scale - eps, y * scale, time)) / (2 * eps);
+  let dndy = (noise(x * scale, y * scale + eps, time) -
+              noise(x * scale, y * scale - eps, time)) / (2 * eps);
+  // Curl = perpendicular to gradient
+  return createVector(dndy, -dndx);
+}
+```
+

+    pixels[idx + 2] = 255 - b;   // invert blue
+  }
+}
+updatePixels();
+```
+
+### Pixel-Level Noise Texture
+
+```javascript
+loadPixels();
+for (let i = 0; i < pixels.length; i += 4) {
+  let x = (i / 4) % width;
+  let y = floor((i / 4) / width);

+  let c = n * 255;
+  pixels[i] = c;
+  pixels[i + 1] = c;
+  pixels[i + 2] = c;
+  pixels[i + 3] = 255;
+}
+updatePixels();
+```
+
+### Built-in Filters
+
+```javascript
+filter(BLUR, 3);        // Gaussian blur (radius)
+filter(THRESHOLD, 0.5); // Black/white threshold
+filter(INVERT);          // Color inversion
+filter(POSTERIZE, 4);    // Reduce color levels
+filter(GRAY);            // Desaturate
+filter(ERODE);           // Thin bright areas
+filter(DILATE);          // Expand bright areas
+filter(OPAQUE);          // Remove transparency
+```
+
+## Texture Generation
+
+### Stippling / Pointillism
+
+```javascript
+function stipple(buffer, density, minSize, maxSize) {
+  buffer.loadPixels();
+  for (let i = 0; i < density; i++) {

+      ellipse(x, y, size);
+    }
+  }

+### Halftone

+  sourceBuffer.loadPixels();
+  background(255);
+  fill(0);
+  noStroke();

+
+### Cross-Hatching
+
+```javascript
+function crossHatch(x, y, w, h, value, spacing) {
+  // value: 0 (dark) to 1 (light)
+  let numLayers = floor(map(value, 0, 1, 4, 0));

+    translate(x + w/2, y + h/2);
+    rotate(angles[layer]);
+    let s = spacing + layer * 2;
+    for (let i = -max(w, h); i < max(w, h); i += s) {
+      line(i, -max(w, h), i, max(w, h));
+    }
+    pop();

+```
+
+## Feedback Loops
+
+### Frame Feedback (Echo/Trail)
+
+```javascript
+let feedback;
+
+function setup() {
+  createCanvas(800, 800);
+  feedback = createGraphics(width, height);
+}
+
+function draw() {
+  // Copy current feedback, slightly zoomed and rotated
+  let temp = feedback.get();
+
+  feedback.push();
+  feedback.translate(width/2, height/2);
+  feedback.scale(1.005);  // slow zoom
+  feedback.rotate(0.002); // slow rotation
+  feedback.translate(-width/2, -height/2);
+  feedback.tint(255, 245);  // slight fade
+  feedback.image(temp, 0, 0);
+  feedback.pop();
+
+  // Draw new content to feedback
+  feedback.noStroke();
+  feedback.fill(255);
+  feedback.ellipse(mouseX, mouseY, 20);
+
+  // Show
+  image(feedback, 0, 0);
+}
+```
+
+### Bloom / Glow (Post-Processing)
+
+Downsample the scene to a small buffer, blur it, overlay additively. Creates soft glow around bright areas. This is the standard generative art bloom technique.
+
+```javascript
+let scene, bloomBuf;
+
+function setup() {
+  createCanvas(1080, 1080);
+  scene = createGraphics(width, height);
+  bloomBuf = createGraphics(width, height);
+}
+
+function draw() {
+  // 1. Render scene to offscreen buffer
+  scene.background(0);
+  scene.fill(255, 200, 100);
+  scene.noStroke();
+  // ... draw bright elements to scene ...
+
+  // 2. Build bloom: downsample → blur → upscale
+  bloomBuf.clear();
+  bloomBuf.image(scene, 0, 0, width / 4, height / 4);  // 4x downsample
+  bloomBuf.filter(BLUR, 6);  // blur the small version
+
+  // 3. Composite: scene + additive bloom
+  background(0);
+  image(scene, 0, 0);           // base layer
+  blendMode(ADD);               // additive = glow
+  tint(255, 80);                // control bloom intensity (0-255)
+  image(bloomBuf, 0, 0, width, height);  // upscale back to full size
+  noTint();
+  blendMode(BLEND);             // ALWAYS reset blend mode
+}
+```
+
+**Tuning:**
+- Downsample ratio (1/4 is standard, 1/8 for softer, 1/2 for tighter)
+- Blur radius (4-8 typical, higher = wider glow)
+- Tint alpha (40-120, controls glow intensity)
+- Update bloom every N frames to save perf: `if (frameCount % 2 === 0) { ... }`
+
+**Common mistake:** Forgetting `blendMode(BLEND)` after the ADD pass — everything drawn after will be additive.
+
+### Trail Buffer Brightness
+
+Trail accumulation via `createGraphics()` + semi-transparent fade rect is the standard technique for particle trails, but **trails are always dimmer than you expect**. The fade rect's alpha compounds multiplicatively every frame.
+
+```javascript
+// The fade rect alpha controls trail length AND brightness:
+trailBuf.fill(0, 0, 0, alpha);
+trailBuf.rect(0, 0, width, height);
+
+// alpha=5  → very long trails, very dim (content fades to 50% in ~35 frames)
+// alpha=10 → long trails, dim
+// alpha=20 → medium trails, visible
+// alpha=40 → short trails, bright
+// alpha=80 → very short trails, crisp
+```
+
+**The trap:** You set alpha=5 for long trails, but particle strokes at alpha=30 are invisible because they fade before accumulating enough density. Either:
+- **Boost stroke alpha** to 80-150 (not the intuitive 20-40)
+- **Reduce fade alpha** but accept shorter trails
+- **Use additive blending** for the strokes: bright particles accumulate, dim ones stay dark
+

+## Advanced Generative Techniques
+
+### L-Systems (Lindenmayer Systems)
+
+Grammar-based recursive growth for trees, plants, fractals.
+
+```javascript
+class LSystem {
+  constructor(axiom, rules) {
+    this.axiom = axiom;
+    this.rules = rules;  // { 'F': 'F[+F]F[-F]F' }
+    this.sentence = axiom;

+
+  generate(iterations) {

+      }
+      this.sentence = next;
+    }
+  }
+
+  draw(len, angle) {
+    for (let ch of this.sentence) {
+      switch (ch) {
+        case 'F': line(0, 0, 0, -len); translate(0, -len); break;
+        case '+': rotate(angle); break;

+  'F': 'FF'
+});
+lsys.generate(5);
+translate(width/2, height);

+```
+
+### Circle Packing
+
+Fill a space with non-overlapping circles of varying size.
+
+```javascript

+
+let circles = [];
+
+function packStep() {

+  for (let attempts = 0; attempts < 100; attempts++) {
+    let x = random(width), y = random(height);
+    let valid = true;
+    for (let c of circles) {

+    }
+    if (valid) { circles.push(new PackedCircle(x, y, 1)); break; }
+  }
+
+  // Grow existing circles
+  for (let c of circles) {
+    if (!c.growing) continue;

+### Voronoi Diagram (Fortune's Algorithm Approximation)
+
+```javascript

+        if (d < minDist) { minDist = d; closest = i; }
+      }
+      let idx = 4 * (y * width + x);
+      let c = colors[closest % colors.length];
+      pixels[idx] = red(c);

+
+### Fractal Trees
+
+```javascript

+
+// Usage

+
+### Strange Attractors
+
+```javascript
+// Clifford Attractor
+function cliffordAttractor(a, b, c, d, iterations) {

+
+### Poisson Disk Sampling
+
+Even distribution that looks natural — better than pure random for placing elements.
+
+```javascript

+
+### createFilterShader (Post-Processing)
+
+Simpler — only needs a fragment shader. Automatically gets the canvas as a texture.
+
+```javascript
+let blurShader;
+
+function setup() {
+  createCanvas(800, 800, WEBGL);
+
+  blurShader = createFilterShader(`
+    precision mediump float;
+    varying vec2 vTexCoord;
+    uniform sampler2D tex0;
+    uniform vec2 texelSize;
+
+    void main() {
+      vec4 sum = vec4(0.0);
+      for (int x = -2; x <= 2; x++) {
+        for (int y = -2; y <= 2; y++) {
+          sum += texture2D(tex0, vTexCoord + vec2(float(x), float(y)) * texelSize);
+        }
+      }
+      gl_FragColor = sum / 25.0;
+    }
+  `);
+}
+
+function draw() {
+  // Draw scene normally
+  background(0);
+  fill(255, 0, 0);
+  sphere(100);
+
+  // Apply post-processing filter
+  filter(blurShader);
+}
+```
+
+### Common Shader Uniforms
+
+```javascript
+myShader.setUniform('uTime', millis() / 1000.0);
+myShader.setUniform('uResolution', [width, height]);
+myShader.setUniform('uMouse', [mouseX / width, mouseY / height]);
+myShader.setUniform('uTexture', myGraphics);  // pass p5.Graphics as texture
+myShader.setUniform('uValue', 0.5);           // float
+myShader.setUniform('uColor', [1.0, 0.0, 0.5, 1.0]); // vec4
+```
+
+### Shader Recipes
+
+**Chromatic Aberration:**
+```glsl
+vec4 r = texture2D(tex0, vTexCoord + vec2(0.005, 0.0));
+vec4 g = texture2D(tex0, vTexCoord);
+vec4 b = texture2D(tex0, vTexCoord - vec2(0.005, 0.0));
+gl_FragColor = vec4(r.r, g.g, b.b, 1.0);
+```
+
+**Vignette:**
+```glsl
+float d = distance(vTexCoord, vec2(0.5));
+float v = smoothstep(0.7, 0.4, d);
+gl_FragColor = texture2D(tex0, vTexCoord) * v;
+```
+
+**Scanlines:**
+```glsl
+float scanline = sin(vTexCoord.y * uResolution.y * 3.14159) * 0.04;
+vec4 col = texture2D(tex0, vTexCoord);
+gl_FragColor = col - scanline;
+```
+
+## Framebuffers
+
+```javascript
+let fbo;
+
+function setup() {
+  createCanvas(800, 800, WEBGL);
+  fbo = createFramebuffer();
+}
+
+function draw() {
+  // Render to framebuffer
+  fbo.begin();
+  clear();
+  rotateY(frameCount * 0.01);
+  box(200);
+  fbo.end();
+
+  // Use framebuffer as texture
+  texture(fbo.color);
+  plane(width, height);
+}
+```
+
+### Multi-Pass Rendering
+
+```javascript
+let sceneBuffer, blurBuffer;
+
+function setup() {
+  createCanvas(800, 800, WEBGL);
+  sceneBuffer = createFramebuffer();
+  blurBuffer = createFramebuffer();
+}
+
+function draw() {
+  // Pass 1: render scene
+  sceneBuffer.begin();
+  clear();
+  lights();
+  rotateY(frameCount * 0.01);
+  box(200);
+  sceneBuffer.end();
+
+  // Pass 2: blur
+  blurBuffer.begin();
+  shader(blurShader);
+  blurShader.setUniform('uTexture', sceneBuffer.color);
+  rect(0, 0, width, height);
+  resetShader();
+  blurBuffer.end();
+
+  // Final: composite
+  texture(blurBuffer.color);

+/**
+ * p5.js Skill — Headless Frame Export
+ *
+ * Captures frames from a p5.js sketch using Puppeteer (headless Chrome).
+ * Uses noLoop() + redraw() for DETERMINISTIC frame-by-frame control.
+ *
+ * IMPORTANT: Your sketch must call noLoop() in setup() and set
+ * window._p5Ready = true when initialized. This script calls redraw()
+ * for each frame capture, ensuring exact 1:1 correspondence between
+ * frameCount and captured frames.
+ *
+ * If the sketch does NOT set window._p5Ready, the script falls back to
+ * a timed capture mode (less precise, may drop/duplicate frames).
+ *
+ * Usage:
+ *   node export-frames.js sketch.html [options]
+ *
+ * Options:
+ *   --output <dir>    Output directory (default: ./frames)
+ *   --width <px>      Canvas width (default: 1920)
+ *   --height <px>     Canvas height (default: 1080)
+ *   --frames <n>      Number of frames to capture (default: 1)
+ *   --fps <n>         Target FPS for timed fallback mode (default: 30)
+ *   --wait <ms>       Wait before first capture (default: 2000)
+ *   --selector <sel>  Canvas CSS selector (default: canvas)
+ *
+ * Examples:
+ *   node export-frames.js sketch.html --frames 1                     # single PNG
+ *   node export-frames.js sketch.html --frames 300 --fps 30          # 10s at 30fps
+ *   node export-frames.js sketch.html --width 3840 --height 2160     # 4K still
+ *
+ * Sketch template for deterministic capture:
+ *   function setup() {
+ *     createCanvas(1920, 1080);
+ *     pixelDensity(1);
+ *     noLoop();                    // REQUIRED for deterministic capture
+ *     window._p5Ready = true;      // REQUIRED to signal readiness
+ *   }
+ *   function draw() { ... }

+# Karpathy's LLM Wiki
+
+Build and maintain a persistent, compounding knowledge base as interlinked markdown files.
+Based on [Andrej Karpathy's LLM Wiki pattern](https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f).
+
+Unlike traditional RAG (which rediscovers knowledge from scratch per query), the wiki
+compiles knowledge once and keeps it current. Cross-references are already there.
+Contradictions have already been flagged. Synthesis reflects everything ingested.
+
+**Division of labor:** The human curates sources and directs analysis. The agent
+summarizes, cross-references, files, and maintains consistency.
+
+## When This Skill Activates
+
+Use this skill when the user:
+- Asks to create, build, or start a wiki or knowledge base
+- Asks to ingest, add, or process a source into their wiki
+- Asks a question and an existing wiki is present at the configured path
+- Asks to lint, audit, or health-check their wiki
+- References their wiki, knowledge base, or "notes" in a research context
+
+## Wiki Location
+
+Configured via `skills.config.wiki.path` in `~/.hermes/config.yaml` (prompted
+during `hermes config migrate` or `hermes setup`):
+
+```yaml
+skills:
+  config:
+    wiki:
+      path: ~/wiki
+```
+
+Falls back to `~/wiki` default. The resolved path is injected when this
+skill loads — check the `[Skill config: ...]` block above for the active value.
+
+The wiki is just a directory of markdown files — open it in Obsidian, VS Code, or
+any editor. No database, no special tooling required.
+
+## Architecture: Three Layers
+
+```
+wiki/
+├── SCHEMA.md           # Conventions, structure rules, domain config
+├── index.md            # Sectioned content catalog with one-line summaries
+├── log.md              # Chronological action log (append-only, rotated yearly)
+├── raw/                # Layer 1: Immutable source material
+│   ├── articles/       # Web articles, clippings
+│   ├── papers/         # PDFs, arxiv papers
+│   ├── transcripts/    # Meeting notes, interviews
+│   └── assets/         # Images, diagrams referenced by sources
+├── entities/           # Layer 2: Entity pages (people, orgs, products, models)
+├── concepts/           # Layer 2: Concept/topic pages
+├── comparisons/        # Layer 2: Side-by-side analyses
+└── queries/            # Layer 2: Filed query results worth keeping
+```
+
+**Layer 1 — Raw Sources:** Immutable. The agent reads but never modifies these.
+**Layer 2 — The Wiki:** Agent-owned markdown files. Created, updated, and
+cross-referenced by the agent.
+**Layer 3 — The Schema:** `SCHEMA.md` defines structure, conventions, and tag taxonomy.
+
+## Resuming an Existing Wiki (CRITICAL — do this every session)
+
+When the user has an existing wiki, **always orient yourself before doing anything**:
+
+① **Read `SCHEMA.md`** — understand the domain, conventions, and tag taxonomy.
+② **Read `index.md`** — learn what pages exist and their summaries.
+③ **Scan recent `log.md`** — read the last 20-30 entries to understand recent activity.
+
+```bash
+WIKI="${wiki_path:-$HOME/wiki}"
+# Orientation reads at session start
+read_file "$WIKI/SCHEMA.md"
+read_file "$WIKI/index.md"
+read_file "$WIKI/log.md" offset=<last 30 lines>
+```
+
+Only after orientation should you ingest, query, or lint. This prevents:
+- Creating duplicate pages for entities that already exist
+- Missing cross-references to existing content
+- Contradicting the schema's conventions
+- Repeating work already logged
+
+For large wikis (100+ pages), also run a quick `search_files` for the topic
+at hand before creating anything new.
+
+## Initializing a New Wiki
+
+When the user asks to create or start a wiki:
+
+1. Determine the wiki path (from config, env var, or ask the user; default `~/wiki`)
+2. Create the directory structure above
+3. Ask the user what domain the wiki covers — be specific
+4. Write `SCHEMA.md` customized to the domain (see template below)
+5. Write initial `index.md` with sectioned header
+6. Write initial `log.md` with creation entry
+7. Confirm the wiki is ready and suggest first sources to ingest
+
+### SCHEMA.md Template
+
+Adapt to the user's domain. The schema constrains agent behavior and ensures consistency:
+
+```markdown
+# Wiki Schema
+
+## Domain
+[What this wiki covers — e.g., "AI/ML research", "personal health", "startup intelligence"]
+
+## Conventions
+- File names: lowercase, hyphens, no spaces (e.g., `transformer-architecture.md`)
+- Every wiki page starts with YAML frontmatter (see below)
+- Use `[[wikilinks]]` to link between pages (minimum 2 outbound links per page)
+- When updating a page, always bump the `updated` date
+- Every new page must be added to `index.md` under the correct section
+- Every action must be appended to `log.md`
+
+## Frontmatter
+  ```yaml
+  ---
+  title: Page Title
+  created: YYYY-MM-DD
+  updated: YYYY-MM-DD
+  type: entity | concept | comparison | query | summary
+  tags: [from taxonomy below]
+  sources: [raw/articles/source-name.md]
+  ---
+  ```
+
+## Tag Taxonomy
+[Define 10-20 top-level tags for the domain. Add new tags here BEFORE using them.]
+
+Example for AI/ML:
+- Models: model, architecture, benchmark, training
+- People/Orgs: person, company, lab, open-source
+- Techniques: optimization, fine-tuning, inference, alignment, data
+- Meta: comparison, timeline, controversy, prediction
+
+Rule: every tag on a page must appear in this taxonomy. If a new tag is needed,
+add it here first, then use it. This prevents tag sprawl.
+
+## Page Thresholds
+- **Create a page** when an entity/concept appears in 2+ sources OR is central to one source
+- **Add to existing page** when a source mentions something already covered
+- **DON'T create a page** for passing mentions, minor details, or things outside the domain
+- **Split a page** when it exceeds ~200 lines — break into sub-topics with cross-links
+- **Archive a page** when its content is fully superseded — move to `_archive/`, remove from index
+
+## Entity Pages
+One page per notable entity. Include:
+- Overview / what it is
+- Key facts and dates
+- Relationships to other entities ([[wikilinks]])
+- Source references
+
+## Concept Pages
+One page per concept or topic. Include:
+- Definition / explanation
+- Current state of knowledge
+- Open questions or debates
+- Related concepts ([[wikilinks]])
+
+## Comparison Pages
+Side-by-side analyses. Include:
+- What is being compared and why
+- Dimensions of comparison (table format preferred)
+- Verdict or synthesis
+- Sources
+
+## Update Policy
+When new information conflicts with existing content:
+1. Check the dates — newer sources generally supersede older ones
+2. If genuinely contradictory, note both positions with dates and sources
+3. Mark the contradiction in frontmatter: `contradictions: [page-name]`
+4. Flag for user review in the lint report
+```
+
+### index.md Template
+
+The index is sectioned by type. Each entry is one line: wikilink + summary.
+
+```markdown
+# Wiki Index
+
+> Content catalog. Every wiki page listed under its type with a one-line summary.
+> Read this first to find relevant pages for any query.
+> Last updated: YYYY-MM-DD | Total pages: N
+
+## Entities
+<!-- Alphabetical within section -->
+
+## Concepts
+
+## Comparisons
+
+## Queries
+```
+
+**Scaling rule:** When any section exceeds 50 entries, split it into sub-sections
+by first letter or sub-domain. When the index exceeds 200 entries total, create
+a `_meta/topic-map.md` that groups pages by theme for faster navigation.
+
+### log.md Template
+
+```markdown
+# Wiki Log
+
+> Chronological record of all wiki actions. Append-only.
+> Format: `## [YYYY-MM-DD] action | subject`
+> Actions: ingest, update, query, lint, create, archive, delete
+> When this file exceeds 500 entries, rotate: rename to log-YYYY.md, start fresh.
+
+## [YYYY-MM-DD] create | Wiki initialized
+- Domain: [domain]
+- Structure created with SCHEMA.md, index.md, log.md
+```
+
+## Core Operations
+
+### 1. Ingest
+
+When the user provides a source (URL, file, paste), integrate it into the wiki:
+
+① **Capture the raw source:**
+   - URL → use `web_extract` to get markdown, save to `raw/articles/`
+   - PDF → use `web_extract` (handles PDFs), save to `raw/papers/`
+   - Pasted text → save to appropriate `raw/` subdirectory
+   - Name the file descriptively: `raw/articles/karpathy-llm-wiki-2026.md`
+
+② **Discuss takeaways** with the user — what's interesting, what matters for
+   the domain. (Skip this in automated/cron contexts — proceed directly.)
+
+③ **Check what already exists** — search index.md and use `search_files` to find
+   existing pages for mentioned entities/concepts. This is the difference between
+   a growing wiki and a pile of duplicates.
+
+④ **Write or update wiki pages:**
+   - **New entities/concepts:** Create pages only if they meet the Page Thresholds
+     in SCHEMA.md (2+ source mentions, or central to one source)
+   - **Existing pages:** Add new information, update facts, bump `updated` date.
+     When new info contradicts existing content, follow the Update Policy.
+   - **Cross-reference:** Every new or updated page must link to at least 2 other
+     pages via `[[wikilinks]]`. Check that existing pages link back.
+   - **Tags:** Only use tags from the taxonomy in SCHEMA.md
+
+⑤ **Update navigation:**
+   - Add new pages to `index.md` under the correct section, alphabetically
+   - Update the "Total pages" count and "Last updated" date in index header
+   - Append to `log.md`: `## [YYYY-MM-DD] ingest | Source Title`
+   - List every file created or updated in the log entry
+
+⑥ **Report what changed** — list every file created or updated to the user.
+
+A single source can trigger updates across 5-15 wiki pages. This is normal
+and desired — it's the compounding effect.
+
+### 2. Query
+
+When the user asks a question about the wiki's domain:
+
+① **Read `index.md`** to identify relevant pages.
+② **For wikis with 100+ pages**, also `search_files` across all `.md` files
+   for key terms — the index alone may miss relevant content.
+③ **Read the relevant pages** using `read_file`.
+④ **Synthesize an answer** from the compiled knowledge. Cite the wiki pages
+   you drew from: "Based on [[page-a]] and [[page-b]]..."
+⑤ **File valuable answers back** — if the answer is a substantial comparison,
+   deep dive, or novel synthesis, create a page in `queries/` or `comparisons/`.
+   Don't file trivial lookups — only answers that would be painful to re-derive.
+⑥ **Update log.md** with the query and whether it was filed.
+
+### 3. Lint
+
+When the user asks to lint, health-check, or audit the wiki:
+
+① **Orphan pages:** Find pages with no inbound `[[wikilinks]]` from other pages.
+```python
+# Use execute_code for this — programmatic scan across all wiki pages
+import os, re
+from collections import defaultdict
+wiki = "<WIKI_PATH>"
+# Scan all .md files in entities/, concepts/, comparisons/, queries/
+# Extract all [[wikilinks]] — build inbound link map
+# Pages with zero inbound links are orphans
+```
+
+② **Broken wikilinks:** Find `[[links]]` that point to pages that don't exist.
+
+③ **Index completeness:** Every wiki page should appear in `index.md`. Compare
+   the filesystem against index entries.
+
+④ **Frontmatter validation:** Every wiki page must have all required fields
+   (title, created, updated, type, tags, sources). Tags must be in the taxonomy.
+
+⑤ **Stale content:** Pages whose `updated` date is >90 days older than the most
+   recent source that mentions the same entities.
+
+⑥ **Contradictions:** Pages on the same topic with conflicting claims. Look for
+   pages that share tags/entities but state different facts.
+
+⑦ **Page size:** Flag pages over 200 lines — candidates for splitting.
+
+⑧ **Tag audit:** List all tags in use, flag any not in the SCHEMA.md taxonomy.
+
+⑨ **Log rotation:** If log.md exceeds 500 entries, rotate it.
+
+⑩ **Report findings** with specific file paths and suggested actions, grouped by
+   severity (broken links > orphans > stale content > style issues).
+
+⑪ **Append to log.md:** `## [YYYY-MM-DD] lint | N issues found`
+
+## Working with the Wiki
+
+### Searching
+
+```bash
+# Find pages by content
+search_files "transformer" path="$WIKI" file_glob="*.md"
+
+# Find pages by filename
+search_files "*.md" target="files" path="$WIKI"
+
+# Find pages by tag
+search_files "tags:.*alignment" path="$WIKI" file_glob="*.md"
+
+# Recent activity
+read_file "$WIKI/log.md" offset=<last 20 lines>
+```
+
+### Bulk Ingest
+
+When ingesting multiple sources at once, batch the updates:
+1. Read all sources first
+2. Identify all entities and concepts across all sources
+3. Check existing pages for all of them (one search pass, not N)
+4. Create/update pages in one pass (avoids redundant updates)
+5. Update index.md once at the end
+6. Write a single log entry covering the batch
+
+### Archiving
+
+When content is fully superseded or the domain scope changes:
+1. Create `_archive/` directory if it doesn't exist
+2. Move the page to `_archive/` with its original path (e.g., `_archive/entities/old-page.md`)
+3. Remove from `index.md`
+4. Update any pages that linked to it — replace wikilink with plain text + "(archived)"
+5. Log the archive action
+
+### Obsidian Integration
+
+The wiki directory works as an Obsidian vault out of the box:
+- `[[wikilinks]]` render as clickable links
+- Graph View visualizes the knowledge network
+- YAML frontmatter powers Dataview queries
+- The `raw/assets/` folder holds images referenced via `![[image.png]]`
+
+For best results:
+- Set Obsidian's attachment folder to `raw/assets/`
+- Enable "Wikilinks" in Obsidian settings (usually on by default)
+- Install Dataview plugin for queries like `TABLE tags FROM "entities" WHERE contains(tags, "company")`
+
+If using the Obsidian skill alongside this one, set `OBSIDIAN_VAULT_PATH` to the
+same directory as the wiki path.
+
+## Pitfalls
+
+- **Never modify files in `raw/`** — sources are immutable. Corrections go in wiki pages.
+- **Always orient first** — read SCHEMA + index + recent log before any operation in a new session.
+  Skipping this causes duplicates and missed cross-references.
+- **Always update index.md and log.md** — skipping this makes the wiki degrade. These are the
+  navigational backbone.
+- **Don't create pages for passing mentions** — follow the Page Thresholds in SCHEMA.md. A name
+  appearing once in a footnote doesn't warrant an entity page.
+- **Don't create pages without cross-references** — isolated pages are invisible. Every page must
+  link to at least 2 other pages.
+- **Frontmatter is required** — it enables search, filtering, and staleness detection.
+- **Tags must come from the taxonomy** — freeform tags decay into noise. Add new tags to SCHEMA.md
+  first, then use them.
+- **Keep pages scannable** — a wiki page should be readable in 30 seconds. Split pages over
+  200 lines. Move detailed analysis to dedicated deep-dive pages.
+- **Ask before mass-updating** — if an ingest would touch 10+ existing pages, confirm
+  the scope with the user first.
+- **Rotate the log** — when log.md exceeds 500 entries, rename it `log-YYYY.md` and start fresh.
+  The agent should check log size during lint.
+- **Handle contradictions explicitly** — don't silently overwrite. Note both claims with dates,
+  mark in frontmatter, flag for user review.

+### Step 0.6: Estimate Compute Budget
+
+Before running experiments, estimate total cost and time:
+
+```
+Compute Budget Checklist:
+- [ ] API costs: (model price per token) × (estimated tokens per run) × (number of runs)
+- [ ] GPU hours: (time per experiment) × (number of experiments) × (number of seeds)
+- [ ] Human evaluation costs: (annotators) × (hours) × (hourly rate)
+- [ ] Total budget ceiling and contingency (add 30-50% for reruns)
+```
+
+Track actual spend as experiments run:
+```python
+# Simple cost tracker pattern
+import json, os
+from datetime import datetime
+
+COST_LOG = "results/cost_log.jsonl"
+
+def log_cost(experiment: str, model: str, input_tokens: int, output_tokens: int, cost_usd: float):
+    entry = {
+        "timestamp": datetime.now().isoformat(),
+        "experiment": experiment,
+        "model": model,
+        "input_tokens": input_tokens,
+        "output_tokens": output_tokens,
+        "cost_usd": cost_usd,
+    }
+    with open(COST_LOG, "a") as f:
+        f.write(json.dumps(entry) + "\n")
+```
+
+**When budget is tight**: Run pilot experiments (1-2 seeds, subset of tasks) before committing to full sweeps. Use cheaper models for debugging pipelines, then switch to target models for final runs.
+
+### Step 0.7: Multi-Author Coordination
+
+Most papers have 3-10 authors. Establish workflows early:
+
+| Workflow | Tool | When to Use |
+|----------|------|-------------|
+| **Overleaf** | Browser-based | Multiple authors editing simultaneously, no git experience |
+| **Git + LaTeX** | `git` with `.gitignore` for aux files | Technical teams, need branch-based review |
+| **Overleaf + Git sync** | Overleaf premium | Best of both — live collab with version history |
+
+**Section ownership**: Assign each section to one primary author. Others comment but don't edit directly. Prevents merge conflicts and style inconsistency.
+
+```
+Author Coordination Checklist:
+- [ ] Agree on section ownership (who writes what)
+- [ ] Set up shared workspace (Overleaf or git repo)
+- [ ] Establish notation conventions (before anyone writes)
+- [ ] Schedule internal review rounds (not just at the end)
+- [ ] Designate one person for final formatting pass
+- [ ] Agree on figure style (colors, fonts, sizes) before creating figures
+```
+
+**LaTeX conventions to agree on early**:
+- `\method{}` macro for consistent method naming
+- Citation style: `\citet{}` vs `\citep{}` usage
+- Math notation: lowercase bold for vectors, uppercase bold for matrices, etc.
+- British vs American spelling

+### Step 1.2b: Deepen the Search (Breadth-First, Then Depth)
+
+A flat search (one round of queries) typically misses important related work. Use an iterative **breadth-then-depth** pattern inspired by deep research pipelines:
+
+```
+Iterative Literature Search:
+
+Round 1 (Breadth): 4-6 parallel queries covering different angles
+  - "[method] + [domain]"
+  - "[problem name] state-of-the-art 2024 2025"
+  - "[baseline method] comparison"
+  - "[alternative approach] vs [your approach]"
+  → Collect papers, extract key concepts and terminology
+
+Round 2 (Depth): Generate follow-up queries from Round 1 learnings
+  - New terminology discovered in Round 1 papers
+  - Papers cited by the most relevant Round 1 results
+  - Contradictory findings that need investigation
+  → Collect papers, identify remaining gaps
+
+Round 3 (Targeted): Fill specific gaps
+  - Missing baselines identified in Rounds 1-2
+  - Concurrent work (last 6 months, same problem)
+  - Key negative results or failed approaches
+  → Stop when new queries return mostly papers you've already seen
+```
+
+**When to stop**: If a round returns >80% papers already in your collection, the search is saturated. Typically 2-3 rounds suffice. For survey papers, expect 4-5 rounds.
+
+**For agent-based workflows**: Delegate each round's queries in parallel via `delegate_task`. Collect results, deduplicate, then generate the next round's queries from the combined learnings.

+### Step 2.5: Design Human Evaluation (If Applicable)
+
+Many NLP, HCI, and alignment papers require human evaluation as primary or complementary evidence. Design this before running automated experiments — human eval often has longer lead times (IRB approval, annotator recruitment).
+
+**When human evaluation is needed:**
+- Automated metrics don't capture what you care about (fluency, helpfulness, safety)
+- Your contribution is about human-facing qualities (readability, preference, trust)
+- Reviewers at NLP venues (ACL, EMNLP) expect it for generation tasks
+
+**Key design decisions:**
+
+| Decision | Options | Guidance |
+|----------|---------|----------|
+| **Annotator type** | Expert, crowdworker, end-user | Match to what your claims require |
+| **Scale** | Likert (1-5), pairwise comparison, ranking | Pairwise is more reliable than Likert for LLM outputs |
+| **Sample size** | Per annotator and total items | Power analysis or minimum 100 items, 3+ annotators |
+| **Agreement metric** | Cohen's kappa, Krippendorff's alpha, ICC | Krippendorff's alpha for >2 annotators; report raw agreement too |
+| **Platform** | Prolific, MTurk, internal team | Prolific for quality; MTurk for scale; internal for domain expertise |
+
+**Annotation guideline checklist:**

+- [ ] Decision criteria for ambiguous cases

+- [ ] Attention checks / gold standard items (10-15% of total)
+- [ ] Qualification task or screening round
+- [ ] Estimated time per item and fair compensation (>= local minimum wage)
+- [ ] IRB/ethics review if required by your institution

+### Step 3.5: Maintain an Experiment Journal
+
+Git commits track what happened, but not the **exploration tree** — the decisions about what to try next based on what you learned. Maintain a structured experiment journal that captures this tree:
+
+```json
+// experiment_journal.jsonl — append one entry per experiment attempt
+{
+  "id": "exp_003",
+  "parent": "exp_001",
+  "timestamp": "2025-05-10T14:30:00Z",

+  "next_steps": ["Try same constraints on Sonnet", "Test without structure template"],
+  "figures": ["figures/exp003_convergence.pdf"]
+}
+```
+
+**Why a journal, not just git?** Git tracks file changes. The journal tracks the reasoning: why you tried X, what you learned, and what that implies for the next experiment. When writing the paper, this tree is invaluable for the Methods section ("we observed X, which motivated Y") and for honest failure reporting.
+
+**Selecting the best path**: When the journal shows a branching tree (exp_001 → exp_002a, exp_002b, exp_003), identify the path that best supports the paper's claims. Document dead-end branches in the appendix as ablations or negative results.
+
+**Snapshot code per experiment**: Copy the experiment script after each run:
+```bash
+cp experiment.py results/exp_003/experiment_snapshot.py

+### Step 4.6: Write the Experiment Log (Bridge to Writeup)
+
+Before moving to paper writing, create a structured experiment log that bridges results to prose. This is the single most important connective tissue between experiments and the writeup — without it, the writing agent has to re-derive the story from raw result files.
+
+**Create `experiment_log.md`** with the following structure:

+### Context Management for Large Projects
+
+A paper project with 50+ experiment files, multiple result directories, and extensive literature notes can easily exceed the agent's context window. Manage this proactively:
+
+**What to load into context per drafting task:**
+
+| Drafting Task | Load Into Context | Do NOT Load |
+|---------------|------------------|-------------|
+| Writing Introduction | `experiment_log.md`, contribution statement, 5-10 most relevant paper abstracts | Raw result JSONs, full experiment scripts, all literature notes |
+| Writing Methods | Experiment configs, pseudocode, architecture description | Raw logs, results from other experiments |
+| Writing Results | `experiment_log.md`, result summary tables, figure list | Full analysis scripts, intermediate data |
+| Writing Related Work | Organized citation notes (Step 1.4 output), .bib file | Experiment files, raw PDFs |
+| Revision pass | Full paper draft, specific reviewer concerns | Everything else |
+
+**Principles:**
+- **`experiment_log.md` is the primary context bridge** — it summarizes everything needed for writing without loading raw data files (see Step 4.6)
+- **Load one section's context at a time** when delegating. A sub-agent drafting Methods doesn't need the literature review notes.
+- **Summarize, don't include raw files.** For a 200-line result JSON, load a 10-line summary table. For a 50-page related paper, load the 5-sentence abstract + your 2-line note about its relevance.
+- **For very large projects**: Create a `context/` directory with pre-compressed summaries:

+    contribution.md          # 1 sentence
+    experiment_summary.md    # Key results table (from experiment_log.md)

+For each section, write a complete draft, then immediately refine it in the same context. This catches local issues (clarity, flow, completeness) while the section is fresh.
+
+**Pass 2 — Global refinement with full-paper context:**
+After all sections are drafted, revisit each section with awareness of the complete paper. This catches cross-section issues: redundancy, inconsistent terminology, narrative flow, and gaps where one section promises something another doesn't deliver.
+
+```
+Second-pass refinement prompt (per section):
+"Review the [SECTION] in the context of the complete paper.
+- Does it fit with the rest of the paper? Are there redundancies with other sections?
+- Is terminology consistent with Introduction and Methods?
+- Can anything be cut without weakening the message?

+**Step 2: Meta-review (Area Chair aggregation)**
+
+Feed all N reviews to a meta-reviewer:
+
+```
+You are an Area Chair at [VENUE]. You have received [N] independent reviews
+of a paper. Your job is to:
+
+1. Identify consensus strengths and weaknesses across reviewers
+2. Resolve disagreements by examining the paper directly
+3. Produce a meta-review that represents the aggregate judgment
+4. Use AVERAGED numerical scores across all reviews
+
+Be conservative: if reviewers disagree on whether a weakness is serious,
+treat it as serious until the authors address it.
+
+Reviews:
+[review_1]
+[review_2]
+...
+```
+
+**Step 3: Reflection loop** (optional, 2-3 rounds)
+
+Each reviewer can refine their review after seeing the meta-review. Use an early termination sentinel: if the reviewer responds "I am done" (no changes), stop iterating.
+
+**Model selection for reviewing**: Reviewing is best done with the strongest available model, even if you wrote the paper with a cheaper one. The reviewer model should be chosen independently from the writing model.
+
+**Few-shot calibration**: If available, include 1-2 real published reviews from the target venue as examples. This dramatically improves score calibration. See [references/reviewer-guidelines.md](references/reviewer-guidelines.md) for example reviews.
+
+### Step 6.1b: Visual Review Pass (VLM)
+
+Text-only review misses an entire class of problems: figure quality, layout issues, visual consistency. If you have access to a vision-capable model, run a separate **visual review** on the compiled PDF:
+
+```
+You are reviewing the visual presentation of this research paper PDF.
+Check for:
+1. Figure quality: Are plots readable? Labels legible? Colors distinguishable?
+2. Figure-caption alignment: Does each caption accurately describe its figure?
+3. Layout issues: Orphaned section headers, awkward page breaks, figures far from their references
+4. Table formatting: Aligned columns, consistent decimal precision, bold for best results
+5. Visual consistency: Same color scheme across all figures, consistent font sizes
+6. Grayscale readability: Would the figures be understandable if printed in B&W?
+
+For each issue, specify the page number and exact location.
+```
+
+This catches problems that text-based review cannot: a plot with illegible axis labels, a figure placed 3 pages from its first reference, inconsistent color palettes between Figure 2 and Figure 5, or a table that's clearly wider than the column width.
+
+### Step 6.1c: Claim Verification Pass
+
+After simulated reviews, run a separate verification pass. This catches factual errors that reviewers might miss:
+
+```
+Claim Verification Protocol:
+1. Extract every factual claim from the paper (numbers, comparisons, trends)
+2. For each claim, trace it to the specific experiment/result that supports it
+3. Verify the number in the paper matches the actual result file
+4. Flag any claim without a traceable source as [VERIFY]
+```
+
+For agent-based workflows: delegate verification to a **fresh sub-agent** that receives only the paper text and the raw result files. The fresh context prevents confirmation bias — the verifier doesn't "remember" what the results were supposed to be.

+### Step 7.9: arXiv & Preprint Strategy
+
+Posting to arXiv is standard practice in ML but has important timing and anonymity considerations.
+
+**Timing decision tree:**
+
+| Situation | Recommendation |
+|-----------|---------------|
+| Submitting to double-blind venue (NeurIPS, ICML, ACL) | Post to arXiv **after** submission deadline, not before. Posting before can technically violate anonymity policies, though enforcement varies. |
+| Submitting to ICLR | ICLR explicitly allows arXiv posting before submission. But don't put author names in the submission itself. |
+| Paper already on arXiv, submitting to new venue | Acceptable at most venues. Do NOT update arXiv version during review with changes that reference reviews. |
+| Workshop paper | arXiv is fine at any time — workshops are typically not double-blind. |
+| Want to establish priority | Post immediately if scooping is a concern — but accept the anonymity tradeoff. |
+
+**arXiv category selection** (ML/AI papers):
+
+| Category | Code | Best For |
+|----------|------|----------|
+| Machine Learning | `cs.LG` | General ML methods |
+| Computation and Language | `cs.CL` | NLP, language models |
+| Artificial Intelligence | `cs.AI` | Reasoning, planning, agents |
+| Computer Vision | `cs.CV` | Vision models |
+| Information Retrieval | `cs.IR` | Search, recommendation |
+
+**List primary + 1-2 cross-listed categories.** More categories = more visibility, but only cross-list where genuinely relevant.
+
+**Versioning strategy:**
+- **v1**: Initial submission (matches conference submission)
+- **v2**: Post-acceptance with camera-ready corrections (add "accepted at [Venue]" to abstract)
+- Don't post v2 during the review period with changes that clearly respond to reviewer feedback
+
+```bash
+# Check if your paper's title is already taken on arXiv
+# (before choosing a title)
+pip install arxiv
+python -c "
+import arxiv
+results = list(arxiv.Search(query='ti:\"Your Exact Title\"', max_results=5).results())
+print(f'Found {len(results)} matches')
+for r in results: print(f'  {r.title} ({r.published.year})')
+"
+```
+
+### Step 7.10: Research Code Packaging
+
+Releasing clean, runnable code significantly increases citations and reviewer trust. Package code alongside the camera-ready submission.
+
+**Repository structure:**
+
+```
+your-method/
+  README.md              # Setup, usage, reproduction instructions
+  requirements.txt       # Or environment.yml for conda

+To reproduce Figure 2: `python scripts/make_figure2.py`
+
+## Citation
+[BibTeX entry]
+```
+
+**Pre-release checklist:**
+```
+- [ ] Code runs from a clean clone (test on fresh machine or Docker)
+- [ ] All dependencies pinned to specific versions
+- [ ] No hardcoded absolute paths
+- [ ] No API keys, credentials, or personal data in repo
+- [ ] README covers setup, reproduction, and citation
+- [ ] LICENSE file present (MIT or Apache 2.0 for max reuse)
+- [ ] Results are reproducible within expected variance
+- [ ] .gitignore excludes data files, checkpoints, logs
+```
+
+**Anonymous code for submission** (before acceptance):
+```bash
+# Use Anonymous GitHub for double-blind review
+# https://anonymous.4open.science/
+# Upload your repo → get an anonymous URL → put in paper
+```
+
+---
+
+## Phase 8: Post-Acceptance Deliverables
+
+**Goal**: Maximize the impact of your accepted paper through presentation materials and community engagement.
+
+### Step 8.1: Conference Poster
+
+Most conferences require a poster session. Poster design principles:
+
+| Element | Guideline |
+|---------|-----------|
+| **Size** | Check venue requirements (typically 24"x36" or A0 portrait/landscape) |
+| **Content** | Title, authors, 1-sentence contribution, method figure, 2-3 key results, conclusion |
+| **Flow** | Top-left to bottom-right (Z-pattern) or columnar |
+| **Text** | Title readable at 3m, body at 1m. No full paragraphs — bullet points only. |
+| **Figures** | Reuse paper figures at higher resolution. Enlarge key result. |
+
+**Tools**: LaTeX (`beamerposter` package), PowerPoint/Keynote, Figma, Canva.
+
+**Production**: Order 2+ weeks before the conference. Fabric posters are lighter for travel. Many conferences now support virtual/digital posters too.
+
+### Step 8.2: Conference Talk / Spotlight
+
+If awarded an oral or spotlight presentation:
+
+| Talk Type | Duration | Content |
+|-----------|----------|---------|
+| **Spotlight** | 5 min | Problem, approach, one key result. Rehearse to exactly 5 minutes. |
+| **Oral** | 15-20 min | Full story: problem, approach, key results, ablations, limitations. |
+| **Workshop talk** | 10-15 min | Adapt based on workshop audience — may need more background. |
+
+**Slide design rules:**
+- One idea per slide
+- Minimize text — speak the details, don't project them
+- Animate key figures to build understanding step-by-step
+- Include a "takeaway" slide at the end (single sentence contribution)
+- Prepare backup slides for anticipated questions
+
+### Step 8.3: Blog Post / Social Media
+
+An accessible summary significantly increases impact:
+
+- **Twitter/X thread**: 5-8 tweets. Lead with the result, not the method. Include Figure 1 and key result figure.
+- **Blog post**: 800-1500 words. Written for ML practitioners, not reviewers. Skip formalism, emphasize intuition and practical implications.
+- **Project page**: HTML page with abstract, figures, demo, code link, BibTeX. Use GitHub Pages.
+
+**Timing**: Post within 1-2 days of paper appearing on proceedings or arXiv camera-ready.
+
+---
+
+## Workshop & Short Papers
+
+Workshop papers and short papers (e.g., ACL short papers, Findings papers) follow the same pipeline but with different constraints and expectations.
+
+### Workshop Papers
+
+| Property | Workshop | Main Conference |
+|----------|----------|-----------------|
+| **Page limit** | 4-6 pages (typically) | 7-9 pages |
+| **Review standard** | Lower bar for completeness | Must be complete, thorough |
+| **Review process** | Usually single-blind or light review | Double-blind, rigorous |
+| **What's valued** | Interesting ideas, preliminary results, position pieces | Complete empirical story with strong baselines |
+| **arXiv** | Post anytime | Timing matters (see arXiv strategy) |
+| **Contribution bar** | Novel direction, interesting negative result, work-in-progress | Significant advance with strong evidence |
+
+**When to target a workshop:**
+- Early-stage idea you want feedback on before a full paper
+- Negative result that doesn't justify 8+ pages
+- Position piece or opinion on a timely topic
+- Replication study or reproducibility report
+
+### ACL Short Papers & Findings
+
+ACL venues have distinct submission types:
+
+| Type | Pages | What's Expected |
+|------|-------|-----------------|
+| **Long paper** | 8 | Complete study, strong baselines, ablations |
+| **Short paper** | 4 | Focused contribution: one clear point with evidence |
+| **Findings** | 8 | Solid work that narrowly missed main conference |
+
+**Short paper strategy**: Pick ONE claim and support it thoroughly. Don't try to compress a long paper into 4 pages — write a different, more focused paper.
+
+---
+
+## Paper Types Beyond Empirical ML
+
+The main pipeline above targets empirical ML papers. Other paper types require different structures and evidence standards. See [references/paper-types.md](references/paper-types.md) for detailed guidance on each type.
+
+### Theory Papers
+
+**Structure**: Introduction → Preliminaries (definitions, notation) → Main Results (theorems) → Proof Sketches → Discussion → Full Proofs (appendix)
+
+**Key differences from empirical papers:**
+- Contribution is a theorem, bound, or impossibility result — not experimental numbers
+- Methods section replaced by "Preliminaries" and "Main Results"
+- Proofs are the evidence, not experiments (though empirical validation of theory is welcome)
+- Proof sketches in main text, full proofs in appendix is standard practice
+- Experimental section is optional but strengthens the paper if it validates theoretical predictions
+
+**Proof writing principles:**
+- State theorems formally with all assumptions explicit
+- Provide intuition before formal proof ("The key insight is...")
+- Proof sketches should convey the main idea in 0.5-1 page
+- Use `\begin{proof}...\end{proof}` environments
+- Number assumptions and reference them in theorems: "Under Assumptions 1-3, ..."
+
+### Survey / Tutorial Papers
+
+**Structure**: Introduction → Taxonomy / Organization → Detailed Coverage → Open Problems → Conclusion
+
+**Key differences:**
+- Contribution is the organization, synthesis, and identification of open problems — not new methods
+- Must be comprehensive within scope (reviewers will check for missing references)
+- Requires a clear taxonomy or organizational framework
+- Value comes from connections between works that individual papers don't make
+- Best venues: TMLR (survey track), JMLR, Foundations and Trends in ML, ACM Computing Surveys
+
+### Benchmark Papers
+
+**Structure**: Introduction → Task Definition → Dataset Construction → Baseline Evaluation → Analysis → Intended Use & Limitations
+
+**Key differences:**
+- Contribution is the benchmark itself — it must fill a genuine evaluation gap
+- Dataset documentation is mandatory, not optional (see Datasheets, Step 5.11)
+- Must demonstrate the benchmark is challenging (baselines don't saturate it)
+- Must demonstrate the benchmark measures what you claim it measures (construct validity)
+- Best venues: NeurIPS Datasets & Benchmarks track, ACL (resource papers), LREC-COLING
+
+### Position Papers
+
+**Structure**: Introduction → Background → Thesis / Argument → Supporting Evidence → Counterarguments → Implications
+
+**Key differences:**
+- Contribution is an argument, not a result
+- Must engage seriously with counterarguments
+- Evidence can be empirical, theoretical, or logical analysis
+- Best venues: ICML (position track), workshops, TMLR

+## When Human Evaluation Is Needed
+
+| Scenario | Human Eval Required? | Notes |
+|----------|---------------------|-------|
+| Text generation quality (fluency, coherence) | **Yes** | Automated metrics (BLEU, ROUGE) correlate poorly with human judgment |
+| Factual accuracy of generated text | **Strongly recommended** | Automated fact-checking is unreliable |
+| Safety/toxicity evaluation | **Yes for nuanced cases** | Classifiers miss context-dependent harm |
+| Preference between two systems | **Yes** | Most reliable method for comparing LLM outputs |
+| Summarization quality | **Yes** | ROUGE doesn't capture faithfulness or relevance well |
+| Task completion (UI, agents) | **Yes** | User studies are the gold standard |
+| Classification accuracy | **Usually no** | Ground truth labels suffice; human eval adds cost without insight |
+| Perplexity or loss comparisons | **No** | Automated metrics are the correct evaluation |
+
+---
+
+## Study Design
+
+### Evaluation Types
+
+| Type | When to Use | Pros | Cons |
+|------|-------------|------|------|
+| **Pairwise comparison** | Comparing two systems | Most reliable, minimizes scale bias | Only compares pairs, quadratic in systems |
+| **Likert scale** (1-5 or 1-7) | Rating individual outputs | Easy to aggregate | Subjective anchoring, scale compression |
+| **Ranking** | Ordering 3+ systems | Captures full preference order | Cognitive load increases with items |
+| **Best-worst scaling** | Comparing many systems efficiently | More reliable than Likert, linear in items | Requires careful item selection |
+| **Binary judgment** | Yes/no decisions (grammatical? factual?) | Simple, high agreement | Loses nuance |
+| **Error annotation** | Identifying specific error types | Rich diagnostic information | Expensive, requires trained annotators |
+
+**Recommendation for most ML papers**: Pairwise comparison is the most defensible. Reviewers rarely question its validity. For Likert scales, always report both mean and distribution.
+
+### Sample Size Planning
+
+**Minimum viable sample sizes:**
+
+| Study Type | Minimum Items | Minimum Annotators | Notes |
+|------------|--------------|-------------------|-------|
+| Pairwise comparison | 100 pairs | 3 per pair | Detects ~10% win rate difference at p<0.05 |
+| Likert rating | 100 items | 3 per item | Enough for meaningful averages |
+| Ranking | 50 sets | 3 per set | Each set contains all systems being compared |
+| Error annotation | 200 items | 2 per item | Higher agreement expected for structured schemes |
+
+**Power analysis** (for planning more precisely):
+
+```python
+from scipy import stats
+import numpy as np
+
+def sample_size_pairwise(effect_size=0.10, alpha=0.05, power=0.80):
+    """
+    Estimate sample size for pairwise comparison (sign test).
+    effect_size: expected win rate difference from 0.50
+    """
+    p_expected = 0.50 + effect_size
+    # Normal approximation to binomial
+    z_alpha = stats.norm.ppf(1 - alpha / 2)
+    z_beta = stats.norm.ppf(power)
+    n = ((z_alpha * np.sqrt(0.25) + z_beta * np.sqrt(p_expected * (1 - p_expected))) ** 2) / (effect_size ** 2)
+    return int(np.ceil(n))
+
+print(f"Sample size for 10% effect: {sample_size_pairwise(0.10)}")  # ~200
+print(f"Sample size for 15% effect: {sample_size_pairwise(0.15)}")  # ~90
+print(f"Sample size for 20% effect: {sample_size_pairwise(0.20)}")  # ~50
+```
+
+### Controlling for Bias
+
+| Bias | Mitigation |
+|------|-----------|
+| **Order bias** (first item preferred) | Randomize presentation order for each annotator |
+| **Length bias** (longer = better) | Control for length or analyze separately |
+| **Anchoring** (first annotation sets scale) | Include warm-up items (not counted) |
+| **Fatigue** (quality drops over time) | Limit session length (30-45 min max), randomize item order |
+| **Annotator expertise** | Report annotator background; use qualification tasks |
+
+---
+
+## Annotation Guidelines
+
+Well-written annotation guidelines are the single biggest factor in evaluation quality. Invest significant time here.
+
+### Structure of Good Guidelines
+
+```markdown
+# [Task Name] Annotation Guidelines
+
+## Overview
+[1-2 sentences describing the task]
+
+## Definitions
+[Define every term annotators will use in their judgments]
+- Quality: [specific definition for this study]
+- Fluency: [specific definition]
+- Factuality: [specific definition]
+
+## Rating Scale
+[For each scale point, provide:]
+- Numeric value
+- Label (e.g., "Excellent", "Good", "Acceptable", "Poor", "Unacceptable")
+- Definition of what qualifies for this rating
+- 1-2 concrete examples at this level
+
+## Examples
+
+### Example 1: [Rating = 5]
+Input: [exact input]
+Output: [exact output]
+Rating: 5
+Explanation: [why this is a 5]
+
+### Example 2: [Rating = 2]
+Input: [exact input]
+Output: [exact output]
+Rating: 2
+Explanation: [why this is a 2]
+
+[Include at least 2 examples per rating level, covering edge cases]
+
+## Edge Cases
+- If the output is [ambiguous case]: [instruction]
+- If the input is [unusual case]: [instruction]
+
+## Common Mistakes
+- Don't [common annotator error]
+- Don't let [bias] influence your rating
+```
+
+### Pilot Testing
+
+**Always run a pilot** before the full study:
+1. 3-5 annotators, 20-30 items
+2. Compute agreement metrics
+3. Discuss disagreements in group session
+4. Revise guidelines based on confusion points
+5. Run second pilot if agreement was poor (<0.40 kappa)
+
+---
+
+## Platforms and Recruitment
+
+| Platform | Best For | Cost | Quality |
+|----------|----------|------|---------|
+| **Prolific** | General annotation, surveys | $8-15/hr | High (academic-focused pool) |
+| **Amazon MTurk** | Large-scale simple tasks | $5-12/hr | Variable (needs strong QC) |
+| **Surge AI** | NLP-specific annotation | $15-25/hr | Very high (trained annotators) |
+| **Scale AI** | Production-quality labeling | Varies | High (managed workforce) |
+| **Internal team** | Domain expertise required | Varies | Highest for specialized tasks |
+| **Upwork/contractors** | Long-term annotation projects | $10-30/hr | Depends on hiring |
+
+**Fair compensation**: Always pay at least the equivalent of local minimum wage for the annotator's location. Many conferences (ACL in particular) now ask about annotator compensation. Paying below minimum wage is an ethics risk.
+
+**Prolific setup (recommended for most ML papers):**
+1. Create study on prolific.co
+2. Set prescreening filters (language, country, approval rate >95%)
+3. Estimate time per task from pilot → set fair payment
+4. Use Prolific's built-in attention checks or add your own
+5. Collect Prolific IDs for quality tracking (but don't share in paper)
+
+---
+
+## Quality Control
+
+### Attention Checks
+
+Include items where the correct answer is unambiguous:
+
+```python
+# Types of attention checks
+attention_checks = {
+    "instructed_response": "For this item, please select 'Strongly Agree' regardless of content.",
+    "obvious_quality": "Rate this clearly ungrammatical text: 'The cat dog house green yesterday.'",  # Should get lowest score
+    "gold_standard": "Items where expert consensus exists (pre-annotated by authors)",
+    "trap_question": "What color is the sky on a clear day? (embedded in annotation interface)"
+}
+
+# Recommended: 10-15% of total items should be checks
+# Exclusion criterion: fail 2+ attention checks → exclude annotator
+```
+
+### Annotator Qualification
+
+For tasks requiring expertise:
+
+```
+Qualification Task Design:
+1. Create a set of 20-30 items with known-correct labels
+2. Require annotators to complete this before the main task
+3. Set threshold: ≥80% agreement with gold labels to qualify
+4. Record qualification scores for reporting
+```
+
+### Monitoring During Collection
+
+```python
+# Real-time quality monitoring
+def monitor_quality(annotations):
+    """Check for annotation quality issues during collection."""
+    issues = []
+    
+    # 1. Check for straight-lining (same answer for everything)
+    for annotator_id, items in annotations.groupby('annotator'):
+        if items['rating'].nunique() <= 1:
+            issues.append(f"Annotator {annotator_id}: straight-lining detected")
+    
+    # 2. Check time per item (too fast = not reading)
+    median_time = annotations['time_seconds'].median()
+    fast_annotators = annotations.groupby('annotator')['time_seconds'].median()
+    for ann_id, time in fast_annotators.items():
+        if time < median_time * 0.3:
+            issues.append(f"Annotator {ann_id}: suspiciously fast ({time:.0f}s vs median {median_time:.0f}s)")
+    
+    # 3. Check attention check performance
+    checks = annotations[annotations['is_attention_check']]
+    for ann_id, items in checks.groupby('annotator'):
+        accuracy = (items['rating'] == items['gold_rating']).mean()
+        if accuracy < 0.80:
+            issues.append(f"Annotator {ann_id}: failing attention checks ({accuracy:.0%})")
+    
+    return issues
+```
+

+
+## Agreement Metrics
+
+### Which Metric to Use
+
+| Metric | When to Use | Interpretation |
+|--------|-------------|---------------|
+| **Cohen's kappa (κ)** | Exactly 2 annotators, categorical | Chance-corrected agreement |
+| **Fleiss' kappa** | 3+ annotators, all rate same items, categorical | Multi-annotator extension of Cohen's |
+| **Krippendorff's alpha (α)** | Any number of annotators, handles missing data | Most general; recommended default |
+| **ICC (Intraclass Correlation)** | Continuous ratings (Likert) | Consistency among raters |
+| **Percent agreement** | Reporting alongside kappa/alpha | Raw agreement (not chance-corrected) |
+| **Kendall's W** | Rankings | Concordance among rankers |
+
+**Always report at least two**: one chance-corrected metric (kappa or alpha) AND raw percent agreement.
+
+### Interpretation Guide
+
+| Value | Krippendorff's α / Cohen's κ | Quality |
+|-------|-------------------------------|---------|
+| > 0.80 | Excellent agreement | Reliable for most purposes |
+| 0.67 - 0.80 | Good agreement | Acceptable for most ML papers |
+| 0.40 - 0.67 | Moderate agreement | Borderline; discuss in paper |
+| < 0.40 | Poor agreement | Revise guidelines and redo annotation |
+
+**Note**: Krippendorff recommends α > 0.667 as minimum for tentative conclusions. NLP tasks with subjective judgments (fluency, helpfulness) typically achieve 0.40-0.70.
+
+### Implementation
+
+```python
+import numpy as np
+from sklearn.metrics import cohen_kappa_score
+import krippendorff  # pip install krippendorff
+
+def compute_agreement(annotations_matrix):
+    """

+    agree_count = 0
+    total_count = 0

+        ratings = annotations_matrix[item, ~np.isnan(annotations_matrix[item, :])]
+        if len(ratings) >= 2:
+            # All annotators agree
+            if len(set(ratings.astype(int))) == 1:
+                agree_count += 1
+            total_count += 1
+    results['percent_agreement'] = agree_count / total_count if total_count > 0 else None
+    
+    return results

+
+## Statistical Analysis for Human Eval
+
+### Pairwise Comparisons
+
+```python
+from scipy import stats
+
+def analyze_pairwise(wins_a, wins_b, ties=0):
+    """
+    Analyze pairwise comparison results.
+    wins_a: number of times system A won

+    n = wins_a + wins_b  # exclude ties
+    
+    # Sign test (exact binomial)
+    p_value = stats.binom_test(wins_a, n, 0.5, alternative='two-sided')

+        'significant': p_value < 0.05,
+        'n_comparisons': n,
+        'ties': ties,
+    }
+```
+
+### Likert Scale Analysis
+
+```python
+def analyze_likert(ratings_a, ratings_b):
+    """Compare Likert ratings between two systems (paired)."""
+    # Wilcoxon signed-rank test (non-parametric, paired)
+    stat, p_value = stats.wilcoxon(ratings_a, ratings_b, alternative='two-sided')

+        'effect_size_r': r,
+        'significant': p_value < 0.05,
+    }
+```
+
+### Multiple Comparisons Correction
+
+When comparing more than two systems:
+
+```python
+from statsmodels.stats.multitest import multipletests
+
+# After computing p-values for all pairs
+p_values = [0.03, 0.001, 0.08, 0.04, 0.15, 0.002]
+rejected, corrected_p, _, _ = multipletests(p_values, method='holm')
+# Use corrected p-values in your paper
+```
+
+---
+
+## Reporting Requirements
+
+Reviewers at NLP venues (ACL, EMNLP, NAACL) check for all of these. ML venues (NeurIPS, ICML) increasingly expect them too.
+
+### Mandatory Reporting
+
+```latex
+% In your paper's human evaluation section:
+\paragraph{Annotators.} We recruited [N] annotators via [platform].
+[Describe qualifications or screening.] Annotators were paid
+\$[X]/hour, above the [country] minimum wage.
+
+\paragraph{Agreement.} Inter-annotator agreement was [metric] = [value]
+(Krippendorff's $\alpha$ = [value]; raw agreement = [value]\%).
+[If low: explain why the task is subjective and how you handle disagreements.]
+
+\paragraph{Evaluation Protocol.} Each [item type] was rated by [N]
+annotators on a [scale description]. We collected [total] annotations
+across [N items]. [Describe randomization and blinding.]
+```
+
+### What Goes in the Appendix
+
+```
+Appendix: Human Evaluation Details
+- Full annotation guidelines (verbatim)
+- Screenshot of annotation interface
+- Qualification task details and threshold
+- Attention check items and failure rates
+- Per-annotator agreement breakdown
+- Full results table (not just averages)
+- Compensation calculation
+- IRB approval number (if applicable)
+```
+
+---
+
+## IRB and Ethics
+
+### When IRB Approval Is Needed
+
+| Situation | IRB Required? |
+|-----------|---------------|
+| Crowdworkers rating text quality | **Usually no** (not "human subjects research" at most institutions) |
+| User study with real users | **Yes** at most US/EU institutions |
+| Collecting personal information | **Yes** |
+| Studying annotator behavior/cognition | **Yes** (they become the subject) |
+| Using existing annotated data | **Usually no** (secondary data analysis) |
+
+**Check your institution's policy.** The definition of "human subjects research" varies. When in doubt, submit an IRB protocol — the review is often fast for minimal-risk studies.
+
+### Ethics Checklist for Human Evaluation
+
+```
+- [ ] Annotators informed about task purpose (not deceptive)
+- [ ] Annotators can withdraw at any time without penalty
+- [ ] No personally identifiable information collected beyond platform ID
+- [ ] Content being evaluated does not expose annotators to harm
+  (if it does: content warnings + opt-out + higher compensation)
+- [ ] Fair compensation (>= equivalent local minimum wage)
+- [ ] Data stored securely, access limited to research team
+- [ ] IRB approval obtained if required by institution
+```
+
+---
+
+## Common Pitfalls
+
+| Pitfall | Problem | Fix |
+|---------|---------|-----|
+| Too few annotators (1-2) | No agreement metric possible | Minimum 3 annotators per item |
+| No attention checks | Can't detect low-quality annotations | Include 10-15% attention checks |
+| Not reporting compensation | Reviewers flag as ethics concern | Always report hourly rate |
+| Using only automated metrics for generation | Reviewers will ask for human eval | Add at least pairwise comparison |
+| Not piloting guidelines | Low agreement, wasted budget | Always pilot with 3-5 people first |
+| Reporting only averages | Hides annotator disagreement | Report distribution and agreement |
+| Not controlling for order/position | Position bias inflates results | Randomize presentation order |
+| Conflating annotator agreement with ground truth | High agreement doesn't mean correct | Validate against expert judgments |

+# Paper Types Beyond Empirical ML
+
+Guide for writing non-standard paper types: theory papers, survey/tutorial papers, benchmark/dataset papers, and position papers. Each type has distinct structure, evidence standards, and venue expectations.
+
+---
+
+## Contents
+
+- [Theory Papers](#theory-papers)
+- [Survey and Tutorial Papers](#survey-and-tutorial-papers)
+- [Benchmark and Dataset Papers](#benchmark-and-dataset-papers)
+- [Position Papers](#position-papers)
+- [Reproducibility and Replication Papers](#reproducibility-and-replication-papers)

+
+## Theory Papers
+
+### When to Write a Theory Paper
+
+Your paper should be a theory paper if:
+- The main contribution is a theorem, bound, impossibility result, or formal characterization
+- Experiments are supplementary validation, not the core evidence
+- The contribution advances understanding rather than achieving state-of-the-art numbers
+
+### Structure
+
+```
+1. Introduction (1-1.5 pages)
+   - Problem statement and motivation
+   - Informal statement of main results
+   - Comparison to prior theoretical work
+   - Contribution bullets (state theorems informally)
+
+2. Preliminaries (0.5-1 page)
+   - Notation table
+   - Formal definitions
+   - Assumptions (numbered, referenced later)
+   - Known results you build on
+
+3. Main Results (2-3 pages)
+   - Theorem statements (formal)
+   - Proof sketches (intuition + key steps)
+   - Corollaries and special cases
+   - Discussion of tightness / optimality
+
+4. Experimental Validation (1-2 pages, optional but recommended)
+   - Do theoretical predictions match empirical behavior?
+   - Synthetic experiments that isolate the phenomenon
+   - Comparison to bounds from prior work
+
+5. Related Work (1 page)
+   - Theoretical predecessors
+   - Empirical work your theory explains
+
+6. Discussion & Open Problems (0.5 page)
+   - Limitations of your results
+   - Conjectures suggested by your analysis
+   - Concrete open problems
+
+Appendix:
+   - Full proofs
+   - Technical lemmas
+   - Extended experimental details
+```
+
+### Writing Theorems
+
+**Template for a well-stated theorem:**
+
+```latex
+\begin{assumption}[Bounded Gradients]\label{assum:bounded-grad}
+There exists $G > 0$ such that $\|\nabla f(x)\| \leq G$ for all $x \in \mathcal{X}$.
+\end{assumption}
+
+\begin{theorem}[Convergence Rate]\label{thm:convergence}
+Under Assumptions~\ref{assum:bounded-grad} and~\ref{assum:smoothness},
+Algorithm~\ref{alg:method} with step size $\eta = \frac{1}{\sqrt{T}}$ satisfies
+\[
+\frac{1}{T}\sum_{t=1}^{T} \mathbb{E}\left[\|\nabla f(x_t)\|^2\right]
+\leq \frac{2(f(x_1) - f^*)}{\sqrt{T}} + \frac{G^2}{\sqrt{T}}.
+\]
+In particular, after $T = O(1/\epsilon^2)$ iterations, we obtain an
+$\epsilon$-stationary point.
+\end{theorem}
+```
+
+**Rules for theorem statements:**
+- State all assumptions explicitly (numbered, with names)
+- Include the formal bound, not just "converges at rate O(·)"
+- Add a plain-language corollary: "In particular, this means..."
+- Compare to known bounds: "This improves over [prior work]'s bound of O(·) by a factor of..."
+
+### Proof Sketches
+
+The proof sketch is the most important part of the main text for a theory paper. Reviewers evaluate whether you have genuine insight or just mechanical derivation.
+
+**Good proof sketch pattern:**
+
+```latex
+\begin{proof}[Proof Sketch of Theorem~\ref{thm:convergence}]
+The key insight is that [one sentence describing the main idea].
+
+The proof proceeds in three steps:
+\begin{enumerate}
+\item \textbf{Decomposition.} We decompose the error into [term A]
+  and [term B] using [technique]. This reduces the problem to
+  bounding each term separately.
+
+\item \textbf{Bounding [term A].} By [assumption/lemma], [term A]
+  is bounded by $O(\cdot)$. The critical observation is that
+  [specific insight that makes this non-trivial].
+
+\item \textbf{Combining.} Choosing $\eta = 1/\sqrt{T}$ balances
+  the two terms, yielding the stated bound.
+\end{enumerate}
+
+The full proof, including the technical lemma for Step 2,
+appears in Appendix~\ref{app:proofs}.
+\end{proof}
+```
+
+**Bad proof sketch**: Restating the theorem with slightly different notation, or just saying "the proof follows standard techniques."
+
+### Full Proofs in Appendix
+
+```latex
+\appendix
+\section{Proofs}\label{app:proofs}
+
+\subsection{Proof of Theorem~\ref{thm:convergence}}
+
+We first establish two technical lemmas.
+
+\begin{lemma}[Descent Lemma]\label{lem:descent}
+Under Assumption~\ref{assum:smoothness}, for any step size $\eta \leq 1/L$:
+\[
+f(x_{t+1}) \leq f(x_t) - \frac{\eta}{2}\|\nabla f(x_t)\|^2 + \frac{\eta^2 L}{2}\|\nabla f(x_t)\|^2.
+\]
+\end{lemma}
+
+\begin{proof}
+[Complete proof with all steps]
+\end{proof}
+
+% Continue with remaining lemmas and main theorem proof
+```
+
+### Common Theory Paper Pitfalls
+
+| Pitfall | Problem | Fix |
+|---------|---------|-----|
+| Assumptions too strong | Trivializes the result | Discuss which assumptions are necessary; prove lower bounds |
+| No comparison to existing bounds | Reviewers can't assess contribution | Add a comparison table of bounds |
+| Proof sketch is just the full proof shortened | Doesn't convey insight | Focus on the 1-2 key ideas; defer mechanics to appendix |
+| No experimental validation | Reviewers question practical relevance | Add synthetic experiments testing predictions |
+| Notation inconsistency | Confuses reviewers | Create a notation table in Preliminaries |
+| Overly complex proofs where simple ones exist | Reviewers suspect error | Prefer clarity over generality |
+
+### Venues for Theory Papers
+
+| Venue | Theory Acceptance Rate | Notes |
+|-------|----------------------|-------|
+| **NeurIPS** | Moderate | Values theory with practical implications |
+| **ICML** | High | Strong theory track |
+| **ICLR** | Moderate | Prefers theory with empirical validation |
+| **COLT** | High | Theory-focused venue |
+| **ALT** | High | Algorithmic learning theory |
+| **STOC/FOCS** | For TCS-flavored results | If contribution is primarily combinatorial/algorithmic |
+| **JMLR** | High | No page limit; good for long proofs |
+
+---
+
+## Survey and Tutorial Papers
+
+### When to Write a Survey
+
+- A subfield has matured enough that synthesis is valuable
+- You've identified connections between works that individual papers don't make
+- Newcomers to the area have no good entry point
+- The landscape has changed significantly since the last survey
+
+**Warning**: Surveys require genuine expertise. A survey by someone outside the field, however comprehensive, will miss nuances and mischaracterize work.
+
+### Structure
+
+```
+1. Introduction (1-2 pages)
+   - Scope definition (what's included and excluded, and why)
+   - Motivation for the survey now
+   - Overview of organization (often with a figure)
+
+2. Background / Problem Formulation (1-2 pages)
+   - Formal problem definition
+   - Notation (used consistently throughout)
+   - Historical context
+
+3. Taxonomy (the core contribution)
+   - Organize methods along meaningful axes
+   - Present taxonomy as a figure or table
+   - Each category gets a subsection
+
+4. Detailed Coverage (bulk of paper)
+   - For each category: representative methods, key ideas, strengths/weaknesses
+   - Comparison tables within and across categories
+   - Don't just describe — analyze and compare
+
+5. Experimental Comparison (if applicable)
+   - Standardized benchmark comparison
+   - Fair hyperparameter tuning for all methods
+   - Not always feasible but significantly strengthens the survey
+
+6. Open Problems & Future Directions (1-2 pages)
+   - Unsolved problems the field should tackle
+   - Promising but underexplored directions
+   - This section is what makes a survey a genuine contribution
+
+7. Conclusion
+```
+
+### Taxonomy Design
+
+The taxonomy is the core intellectual contribution of a survey. It should:
+
+- **Be meaningful**: Categories should correspond to real methodological differences, not arbitrary groupings
+- **Be exhaustive**: Every relevant paper should fit somewhere
+- **Be mutually exclusive** (ideally): Each paper belongs to one primary category
+- **Have informative names**: "Attention-based methods" > "Category 3"
+- **Be visualized**: A figure showing the taxonomy is almost always helpful
+
+**Example taxonomy axes for "LLM Reasoning" survey:**
+- By technique: chain-of-thought, tree-of-thought, self-consistency, tool use
+- By training requirement: prompting-only, fine-tuned, RLHF
+- By reasoning type: mathematical, commonsense, logical, causal
+
+### Writing Standards
+
+- **Cite every relevant paper** — authors will check if their work is included
+- **Be fair** — don't dismiss methods you don't prefer
+- **Synthesize, don't just list** — identify patterns, trade-offs, open questions
+- **Include a comparison table** — even if qualitative (features/properties checklist)
+- **Update before submission** — check arXiv for papers published since you started writing
+
+### Venues for Surveys
+
+| Venue | Notes |
+|-------|-------|
+| **TMLR** (Survey track) | Dedicated survey submissions; no page limit |
+| **JMLR** | Long format, well-respected |
+| **Foundations and Trends in ML** | Invited, but can be proposed |
+| **ACM Computing Surveys** | Broad CS audience |
+| **arXiv** (standalone) | No peer review but high visibility if well-done |
+| **Conference tutorials** | Present as tutorial at NeurIPS/ICML/ACL; write up as paper |
+
+---
+
+## Benchmark and Dataset Papers
+
+### When to Write a Benchmark Paper
+
+- Existing benchmarks don't measure what you think matters
+- A new capability has emerged with no standard evaluation
+- Existing benchmarks are saturated (all methods score >95%)
+- You want to standardize evaluation in a fragmented subfield
+
+### Structure
+
+```
+1. Introduction
+   - What evaluation gap does this benchmark fill?
+   - Why existing benchmarks are insufficient
+
+2. Task Definition
+   - Formal task specification
+   - Input/output format
+   - Evaluation criteria (what makes a good answer?)
+
+3. Dataset Construction
+   - Data source and collection methodology
+   - Annotation process (if human-annotated)
+   - Quality control measures
+   - Dataset statistics (size, distribution, splits)
+
+4. Baseline Evaluation
+   - Run strong baselines (don't just report random/majority)
+   - Show the benchmark is challenging but not impossible
+   - Human performance baseline (if feasible)
+
+5. Analysis
+   - Error analysis on baselines
+   - What makes items hard/easy?
+   - Construct validity: does the benchmark measure what you claim?
+
+6. Intended Use & Limitations
+   - What should this benchmark be used for?
+   - What should it NOT be used for?
+   - Known biases or limitations
+
+7. Datasheet (Appendix)
+   - Full datasheet for datasets (Gebru et al.)
+```
+
+### Evidence Standards
+
+Reviewers evaluate benchmarks on different criteria than methods papers:
+
+| Criterion | What Reviewers Check |
+|-----------|---------------------|
+| **Novelty of evaluation** | Does this measure something existing benchmarks don't? |
+| **Construct validity** | Does the benchmark actually measure the stated capability? |
+| **Difficulty calibration** | Not too easy (saturated) or too hard (random performance) |
+| **Annotation quality** | Agreement metrics, annotator qualifications, guidelines |
+| **Documentation** | Datasheet, license, maintenance plan |
+| **Reproducibility** | Can others use this benchmark easily? |
+| **Ethical considerations** | Bias analysis, consent, sensitive content handling |
+
+### Dataset Documentation (Required)
+
+Follow the Datasheets for Datasets framework (Gebru et al., 2021):
+
+```
+Datasheet Questions:
+1. Motivation
+   - Why was this dataset created?
+   - Who created it and on behalf of whom?
+   - Who funded the creation?
+
+2. Composition
+   - What do the instances represent?
+   - How many instances are there?
+   - Does it contain all possible instances or a sample?
+   - Is there a label? If so, how was it determined?
+   - Are there recommended data splits?
+
+3. Collection Process
+   - How was the data collected?
+   - Who was involved in collection?
+   - Over what timeframe?
+   - Was ethical review conducted?
+
+4. Preprocessing
+   - What preprocessing was done?
+   - Was the "raw" data saved?
+
+5. Uses
+   - What tasks has this been used for?
+   - What should it NOT be used for?
+   - Are there other tasks it could be used for?
+
+6. Distribution
+   - How is it distributed?
+   - Under what license?
+   - Are there any restrictions?
+
+7. Maintenance

+
+## Position Papers
+
+### When to Write a Position Paper
+
+- You have an argument about how the field should develop
+- You want to challenge a widely-held assumption
+- You want to propose a research agenda based on analysis
+- You've identified a systematic problem in current methodology
+
+### Structure
+
+```
+1. Introduction
+   - State your thesis clearly in the first paragraph
+   - Why this matters now
+
+2. Background
+   - Current state of the field
+   - Prevailing assumptions you're challenging
+
+3. Argument
+   - Present your thesis with supporting evidence
+   - Evidence can be: empirical data, theoretical analysis, logical argument,
+     case studies, historical precedent
+   - Be rigorous — this isn't an opinion piece
+
+4. Counterarguments
+   - Engage seriously with the strongest objections
+   - Explain why they don't undermine your thesis
+   - Concede where appropriate — it strengthens credibility
+
+5. Implications
+   - What should the field do differently?
+   - Concrete research directions your thesis suggests
+   - How should evaluation/methodology change?
+
+6. Conclusion
+   - Restate thesis
+   - Call to action
+```
+
+### Writing Standards
+
+- **Lead with the strongest version of your argument** — don't hedge in the first paragraph
+- **Engage with counterarguments honestly** — the best position papers address the strongest objections, not the weakest
+- **Provide evidence** — a position paper without evidence is an editorial
+- **Be concrete** — "the field should do X" is better than "more work is needed"
+- **Don't straw-man existing work** — characterize opposing positions fairly
+
+### Venues for Position Papers
+
+| Venue | Notes |
+|-------|-------|
+| **ICML** (Position track) | Dedicated track for position papers |
+| **NeurIPS** (Workshop papers) | Workshops often welcome position pieces |
+| **ACL** (Theme papers) | When your position aligns with the conference theme |
+| **TMLR** | Accepts well-argued position papers |
+| **CACM** | For broader CS audience |
+
+---
+
+## Reproducibility and Replication Papers
+
+### When to Write a Reproducibility Paper
+
+- You attempted to reproduce a published result and succeeded/failed
+- You want to verify claims under different conditions
+- You've identified that a popular method's performance depends on unreported details
+
+### Structure
+
+```
+1. Introduction
+   - What paper/result are you reproducing?
+   - Why is this reproduction valuable?
+
+2. Original Claims
+   - State the exact claims from the original paper
+   - What evidence was provided?
+
+3. Methodology
+   - Your reproduction approach
+   - Differences from original (if any) and why
+   - What information was missing from the original paper?
+
+4. Results
+   - Side-by-side comparison with original results
+   - Statistical comparison (confidence intervals overlap?)
+   - What reproduced and what didn't?
+
+5. Analysis
+   - If results differ: why? What's sensitive?
+   - Hidden hyperparameters or implementation details?
+   - Robustness to seed, hardware, library versions?
+
+6. Recommendations
+   - For original authors: what should be clarified?
+   - For practitioners: what to watch out for?
+   - For the field: what reproducibility lessons emerge?
+```
