supabaseClient.from('shops').select('count')
  .then(r => console.log('✓ Connected'))
  .catch(e => console.error('✗ Error:', e))
```

### Issue: Service Worker not registering
**Solution**: 
```javascript
// Check HTTPS is enabled
if (location.protocol !== 'https:' && location.hostname !== 'localhost') {
  console.error('Service Worker requires HTTPS');
}
```

### Issue: Offline mode not working
**Solution**:
```javascript
// Verify offline-sync.js is loaded
console.log(typeof OfflineSyncManager)  // Should be 'function'
console.log(navigator.serviceWorker)   // Should exist
```

### Issue: Products not displaying
**Solution**:
```sql
-- Enable RLS policy for public read
CREATE POLICY "Allow public read" ON inventory 
  FOR SELECT USING (true);
