✅ facr_club_info.json
✅ facr_tables.json

    ↓
Database updated
    ↓
Prefetch triggered (manual or automatic)
    ↓
JSON cache files generated (/cache/prefetch/*.json)
    ↓
Frontend loads from cache (faster)
    ↓
Fallback to API if cache missing

Status: ✅ OPTIMIZED - Caching reduces load times

---

🎯 Key Integration Points

1. HomePage.tsx Integration

Lines 186-491: Main data loading effect

• Loads all content types
• Falls back gracefully
• Uses prefetch cache when available

2. Settings Propagation

All components use:

const { settings } = useSettings();
// OR
const settings = await getPublicSettings();

3. Image URL Resolution

All components use:

import { assetUrl } from '../utils/url';
const imageUrl = assetUrl(relativeUrl) || fallbackUrl;
