24 files, -319 LoC. Behaviour preserved, 369/369 tests green. - hermes-ink caches: shared lruEvict helper for the four parallel LRU caches (stringWidth, wrapText, sliceAnsi, lineWidth); touch-on-read stays inlined per cache; tightened output.ts skip-slice fast path. - wheelAccel: trimmed provenance header, collapsed env parsing, ternary dispatch in computeWheelStep. - perfPane: folded ensureLogDir into once-flag, spread-with-overrides for fastPath/phases instead of full rebuilds. - env: extracted truthy() (used 4×). - virtualHeights: collapsed user/diff/slash height bumps; trail+todos estimate. - useInputHandlers: scrollIdleTimer cleanup on unmount, ?? undefined shorthand. - useMainApp: dropped dead liveTailVisible IIFE and liveProgress indirection. - appLayout, markdown, messageLine, entry: vertical rhythm, dropped narration comments, inlined one-shot vars. - fix: empty catch blocks → /* best-effort */ for no-empty lint.
