Backlit Shadowbox Layers
Turn a JSON sheet into a silent paper-lightbox film: a multi-layer shadowbox sits in the frame, paper sheets stack ridge over lantern over moon, a hidden warm lamp ignites layer by layer, lit paper shows its pulp fibres, and the pull-out at the end reveals the whole scene was a glowing box on a dark desk.
How it works
npm install inside the Skill folder, then build.mjs → validate + assemble the page
stills.mjs for a contact sheet; iterate until each layer reads and the lamp ladder works
render.mjs → film.mp4, verified by ffprobe + full decode
