- Track Needle/MenuScene/dist and Needle/SampleScene/dist for container deploys - Dockerfile copies pre-built dist (no npm in image); rebuild with npm run build before commit - Fix Needle .gitignore: /assets/ so dist/assets is not ignored - Git LFS: track *.wasm; relax .dockerignore so dist is sent as build context Made-with: Cursor
