Performance Testing Scenarios

Format: Test your application under different network conditions.

Test scenarios:

1. Fast WiFi (ideal conditions)
2. Slow 3G (Chrome DevTools > Network > Slow 3G)
3. Offline (how does the app behave when disconnected?)
4. High latency (200ms+ delay)

For each scenario, record:
- First-screen load time
- Interaction response time
- Image loading status
- Feature availability

Core lesson: Your app doesn't run on your computer — it runs on your users' various devices and network conditions.
