Equation Morph
A step-by-step derivation film: LaTeX steps morph into one another — terms that persist glide to their new slot while unmatched terms fade. Silent 1080p.
How it works
Write a sheet.json: a title and 2–12 steps of LaTeX, with a stable key on each term that persists between steps.
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.
