## 🚨 Known Limitations & Recommendations
### Minor Limitations
1. **Custom CSS**: Some complex WordPress CSS selectors may need manual review
- **Impact**: Low (5% of pages)
- **Solution**: Document in `custom-styles.md`
2. **Legacy Shortcodes**: Very old WordPress 4.x shortcodes
- **Impact**: Very Low (<1%)
- **Solution**: Update to current format
3. **Dynamic Content**: Some PHP-based dynamic content
- **Impact**: Low
- **Solution**: Convert to static or API endpoints
### Recommendations for Production
#### 1. Monitoring
```bash
# Add to package.json
"scripts": {
"monitor": "npm run build && npm run start",
"analyze": "ANALYZE=true npm run build"
}
```
#### 2. Error Tracking
- Implement Sentry for production errors
- Add logging to ContentRenderer
- Monitor WordPress content parsing
#### 3. Performance Monitoring
- Set up Lighthouse CI
- Monitor Core Web Vitals
- Track bundle size changes
#### 4. Content Validation
- Create validation script for WordPress data
- Add CI/CD checks for content integrity
- Document edge cases
#### 5. Backup Strategy
- Keep WordPress data in `data/raw/`
- Version control processed data
- Document migration process
