# React Component Rules
- Use functional components with explicit return types
- Define props interface directly above the component
- Export components as named exports, never default
- Use Tailwind CSS utility classes exclusively

# Backend Rules
## Stack
- Python 3.12 with FastAPI
- SQLAlchemy 2.0 with async sessions
- Alembic for migrations
- pytest for testing
## Conventions
- Use type hints on all function signatures
- Async endpoints by default
- Pydantic v2 models for request/response schemas
- Repository pattern for database access
## File Structure
- app/api/routes/ — API endpoints
- app/models/ — SQLAlchemy models
- app/schemas/ — Pydantic schemas
- app/services/ — Business logic
