Distortion & Grain

Produce a single self-contained index.html — A vertical gallery (Three.js) where planes bend with scroll velocity, ripple under the cursor via simplex noise, and carry a film grain.

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.
