 ### Integration Tests

 - Test API endpoints return correctly shaped data
 - Verify all fields are present in responses

 ### Manual Testing

 - Test each page/view that displays users, cards, and collections

 ## Migration Notes
 
 ### Breaking Changes
+
 - All response types have changed
 - Frontend code consuming these types will need updates
 - Any DTOs imported from responses.ts will need to be updated
 
 ### Backwards Compatibility
+
 - No backwards compatibility at API client level
 - This is a one-time migration
 - Coordinate with frontend team for deployment
