# Halftone Drift

Produce a single self-contained `index.html` — A self-contained WebGL2 hero: a flowing field screened through a rotated halftone dot grid into a duotone print aesthetic; move the cursor to bend the drift.

## 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.
