- Dockerfile: node:22-bookworm-slim + Python venv with trimesh for the 3MF->GLB sidecar (PYTHON_BIN env points the converter at it) - docker-compose.yml: app + postgres 16 with healthcheck/depends_on, named volumes for pgdata/uploads/thumbnails/glb, token env passthrough - .dockerignore, tools/requirements.txt - converter.js honours PYTHON_BIN (defaults to local venv) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
