- All services rewritten to async with pg Pool
- Data imported (50 recipes, 8 categories)
- better-sqlite3 removed

Frontend:

- HouseholdCard (create, join via code, manage members, leave)
- Shopping scope toggle (personal/household)
- IngredientPickerModal (smart add with basics filter)
- Auth token auto-attached to all API calls (token.ts)
- Removed PlaceholderPage

Infrastructure:
- Docker Compose (backend + frontend + postgres)
- Dockerfile for backend (node:22-alpine + tsx)
- Dockerfile for frontend (vite build + nginx)
- nginx.conf with API proxy + SPA fallback
- .env.example for production secrets

Spec:
