Bug A: Media Library thumbnails were gray because <img src> cannot send JWT auth headers. Added useAuthBlob() hook (fetch + createObjectURL) in MediaBrowser.tsx. Also fixed publish_asset Celery task to populate product_id + cad_file_id on MediaAsset for thumbnail fallback resolution. Bug B: Product dimensions now shown in Product Details card with Ruler icon and "from CAD" label when cad_mesh_attributes.dimensions_mm exists. Bug C: Replaced 128×128 CAD thumbnail with InlineCadViewer component. Queries gltf_geometry MediaAssets, fetches GLB via auth fetch → blob URL → Three.js Canvas with OrbitControls. Falls back to thumbnail + "Load 3D Model" button. Polling when GLB generation is in progress. Bug D: trimesh was in [cad] optional extra but Dockerfile only installed [dev]. Changed to pip install -e ".[dev,cad]" — trimesh now available in backend container, GLB + Colors export works. Also added bbox extraction (STL-first numpy parsing) in render_step_thumbnail and admin "Re-extract CAD Metadata" bulk endpoint. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
