Three.js viewer supporting glb/gltf/obj/fbx/dae/ifc/ply via both server (SSR) and drag&drop (CSR) paths. - Streaming OBJ parser (src/viewer/objStream.ts) for files past the V8 max string length (>~1GB text) that OBJLoader can't handle; indexed geometry, per-vertex color from MTL Kd, float64 recenter baked in. - In-viewer float64 recenter (objRecenter.ts) for huge CAD/survey coordinates (~1e8) so float32 vertex buffers keep precision (no cracked faces). - Z-up right-handed world; Y-up formats rotated on load. - OBJ+MTL+texture drag&drop (LoadingManager URL-modifier maps dropped images). - OrbitControls ground-plane panning (road/rail alignment workflow). - UI: Zoom Fit, perspective/orthographic toggle, feature-edge outline. - DoubleSide for CAD OBJ; PLY mesh + point-cloud support.

description: Build + smoke-test the viewer: typecheck, production build, and a headless load of a sample asset to confirm perceived load < 3s.
Run, in order, quoting real output:
- Typecheck / lint (e.g.
npm run build— Vite runs tsc + bundle). Must exit 0. - Production build artifact exists under
dist/. - Headless load smoke: serve
dist/, load a sample asset (server path) via Puppeteer/playwright OR a node script using the viewer, measure time-to-first-render. Assert < 3000ms perceived. - (If a local-file path exists) simulate a drop of a sample GLB and confirm load + revoke.
Append timings to PROGRESS.md. If any step fails, do not mark the work done — report the failure output.
Arguments: $ARGUMENTS — optional asset path or flag to skip headless (--no-headless).
