## Next Steps

### Immediate (Ready to Execute)
1. **Start Local Server:**
   ```bash
   php -S localhost:8003
   ```

2. **Run Tests:**
   - Follow `docs/guides/TESTING_GUIDE.md`
   - Test functional requirements
   - Run performance tests
   - Validate HTML and schema

3. **Deploy:**
   - All optimizations are production-ready
   - No breaking changes introduced
   - Backward compatible

### Future Optimizations (Optional)
1. **SVG Externalization:** Replace static SVGs with `<img>` tags (potential 549KB reduction)
2. **HTML Structure:** Further reduce nesting depth (requires careful testing)
3. **Content Expansion:** Add FAQ content and enhance descriptions

## Quick Reference

### Test Locally
