  - [ ] Verify the list/table loads with paginated data
  - [ ] Verify sorting and filtering controls work correctly
  - [ ] Verify clicking a row navigates to the detail view
- **Edge cases**:
  - [ ] Verify graceful handling when backend API is unavailable (error state)
  - [ ] Verify responsive layout at different viewport sizes
  - [ ] Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
