Pop-up Book Fold
A macro-filmed pop-up book in code: a hardcover on a warm desk opens into a stage — flat die-cut cards fold up back to front, pull-tab tricks slide and drop props on strings, paper actors walk the page, and whole scenes change on a real curling page turn.
How it works
Author a sheet (JSON): the spreads, the pieces, the tab tricks, the camera
The build validates it and bakes the deterministic renderer into one HTML page
Render in pinned headless Chromium — same sheet, same frames on every machine
