Chain Reaction Film
A deterministic Rube-Goldberg chain film: 3–7 stages laid left-to-right, each triggered by the previous — keypress, marble-drop, toggle, cards, send, notify. Silent 1080p.
How it works
Write a sheet.json: a title, 3–7 stages with kinds/labels, stage duration and palette.
node scripts/build.mjs sheet.json --out build/ bakes the deterministic page.
node scripts/render.mjs --build build --out film.mp4 renders and verifies the silent MP4.
