COMPREHENSIVE TESTING:
Once all steps complete:
- Test complete feature flow start to finish
- Test integration with other existing features
- Test on different browsers
- Test on mobile viewport/devices
- Test edge cases missed during individual steps
- Test error scenarios and recovery
- Verify nothing else broke
- Have someone else test (fresh eyes catch bugs)
