- Add inline comments to docker-compose.yml explaining the 5 key rules (expose vs ports, DB host, DB name persistence, no Traefik labels) - Add comments to Dockerfile explaining multi-stage build, layer caching, and why .dockerignore excludes client/dist - Add comments to .dockerignore explaining each exclusion - Fix dev script: use nodemon (auto-restart) instead of node for server.js - Add postinstall script to auto-install client deps (cd client && npm install) - Fix SPA fallback: bare return → next() to prevent hanging requests - Add root package-lock.json for deterministic server dependency installs - Remove committed tsconfig.tsbuildinfo build artifact, add *.tsbuildinfo to .gitignore - Update README: simpler install (npm install handles everything), reference SAAC_DEPLOYMENT.md, use npx instead of pnpm dlx for shadcn components
