Chat → Claude writes a JSCAD script → sandboxed Web Worker executes it →
live three.js preview + STL export. Parametric // @param comments become
live sliders. Server-side repair loop fixes geometry errors before the user
sees them.
- src/worker: Hono API, Claude orchestration (prompt-cached system prompt),
/api/generate + /api/repair
- src/client: React + react-three-fiber viewport, JSCAD engine Web Worker
- Radical-branded (red #FF2D55 on #0B0B09, Syne + IBM Plex Mono)
Engine validated end-to-end: mug model → 3256-triangle valid binary STL.
