🔧 STABLE CAMERA FEED TEST

This test verifies the following fixes:
✅ Camera feed no longer shrinks excessively
✅ Detection animations don't shake
✅ Modern white theme with proper layout
✅ Stable frame processing and display
✅ Debounced canvas resizing
✅ Smooth, stable animations

Instructions:
1. Click 'Start Monitoring' to begin
2. Try resizing the window - camera feed should remain stable
3. Observe that animations are smooth and don't shake
4. The camera feed maintains a minimum size
5. UI remains responsive with stable performance

Expected Results:
- Camera feed stays large and centered
- No excessive shrinking below minimum size
- Animations are smooth without jitter
- Window resizing doesn't cause shaking
- Modern white theme with proper spacing
