CompassCAD Mobile

This is where CompassCAD will develop its mobile lineup with the codename Undifer (because I got no more names to come up with)

Engine & renderer (merged from NextDesktop)

app/editor/engine/ is the NextDesktop engine. Engine.ts is generated:

git clone https://github.com/CompassCAD/NextDesktop ../NextDesktop
bun run sync-engine ../NextDesktop    # re-run after every upstream merge

The engine only talks to Context2DLike (app/editor/render), implemented by:

• GLESBackend (default): CPU tessellation + one batched GLES draw per frame via expo-gl.
• Canvas2DBackend: the old react-native-canvas path, kept as fallback (/editor?backend=canvas2d).

bun install
bun run typecheck && bun test
bunx expo run:android   # or: bunx expo start --dev-client
