Expand the pixel-art skill from 2 presets (arcade, snes) to 14 presets with hardware-accurate palettes (NES, Game Boy, PICO-8, C64, Apple II, MS Paint, CRT mono), plus a procedural video overlay pipeline. Ported from Synero/pixel-art-studio (MIT). Full attribution in ATTRIBUTION.md. What's in: - scripts/palettes.py — 28 named RGB palettes (hardware + artistic) - scripts/pixel_art.py — 14 presets, named palette support, CLI - scripts/pixel_art_video.py — 12 animation scenes (stars, rain, fireflies, snow, embers, lightning, etc.) → MP4/GIF via ffmpeg - references/palettes.md — palette catalog - SKILL.md — clarify-tool workflow (offer style, then optional scene) What's out (intentional): - Wu's quantizer (PIL's built-in quantize suffices) - Sobel edge-aware downsample (scipy dep not worth it) - Atkinson/Bayer dither (would need numpy reimpl) - Pollinations text-to-image (Hermes uses image_generate instead) Video pipeline uses subprocess.run with check=True (replaces os.system) and tempfile.TemporaryDirectory (replaces manual cleanup).
