## 💡 Best Practices & Recommendations

### Development Workflow
1. **Create feature branch** for each phase
2. **Daily commits** with clear messages
3. **Code reviews** before merging
4. **Test-driven development** (write tests first)
5. **Continuous integration** (automated tests)

### Version Control
```bash
git checkout -b feature/SUB-4-homepage
# Branch per phase:
git checkout -b feature/SUB-4-phase-1-foundation
git checkout -b feature/SUB-4-phase-5-modal
```

### Code Quality
- ✅ Follow codebase conventions (CodeIgniter 4)
- ✅ Use type hints (PHP 8.2)
- ✅ Write meaningful comments
- ✅ Follow naming conventions
- ✅ Use constants for magic strings
- ✅ Handle errors gracefully

### Testing Strategy
1. **Unit tests** for each function/method
2. **Integration tests** for API workflows
3. **E2E tests** for user journeys
4. **Manual testing** for UI/UX
5. **Security testing** for vulnerabilities

### Performance
- Profile before optimizing
- Cache aggressively
- Paginate large datasets
- Optimize database queries (EXPLAIN)
- Monitor in production
