# Holographic Foil

Produce a single self-contained `index.html` — A self-contained WebGL2 hero: thin-film interference over a crushed-foil surface whose palette shifts with the viewing angle; move the cursor to tilt the film.

## Why this is a powered artifact

OpenDesign detects `getContext('webgl2')` / heavy WebGL and renders this file in **powered preview** (a cross-origin-isolated iframe). The full GPU + scroll pipeline runs; no opaque-sandbox workarounds are needed.
