## 🚨 Troubleshooting

### **Still slow on mobile?**
```
1. Check: Network tab for slowest resource
2. If CDN slow → use different CDN
3. If database slow → optimize queries
4. Clear browser cache: Settings → Privacy
```

### **Hamburger not working?**
```
1. Hard refresh: Ctrl+Shift+R
2. Check console: F12 → Console (errors?)
3. Inspect element: F12 → verify classes
```

### **Service Worker not active?**
```
1. DevTools → Application → Service Workers
2. Should show: "activated and running"
3. If not: Unregister → Hard refresh → Reload
```

## 📞 Support Commands

### **Check Everything:**
```javascript
// Performance
console.log('Load Time:', window.performance.timing.loadEventEnd - window.performance.timing.navigationStart, 'ms');

// Service Worker
navigator.serviceWorker.getRegistrations().then(r => console.log('SW Active:', !!r[0]?.active));

// Cache
caches.keys().then(k => console.log('Caches:', k));
