whiteboard
Whiteboard engine
Every frame is a pure function of time t. studio.html loads src/kit.js (shared ReelMimic runtime: timeline,
timing/motion helpers, camera, render hooks), src/whiteboard.js (the look: board, marker strokes, drawOn,
handwriting, icons, hand, transitions, captions), src/cast.js (characters) and your scene files. render.mjs drives
headless Chrome for contact sheets / crops / frames and ffmpeg encodes the MP4.
Read GUIDE.md in full before designing anything — it has the look rules, the complete API with
examples, the character system and the review checklist. Look at the model sheets: docs/faces.jpg (16 expressions
× 2 characters), docs/poses.jpg (views, walk, jump, props), docs/kit.jpg (icons, strokes, fills, text) and
docs/demo-sheet.jpg (the demo).
