🚨 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

# 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
