- Add cursor-pointer to all clickable buttons and interactive elements
- Add focus:ring-2 focus:ring-primary/blue focus:outline-none to all buttons
- Add aria-label to icon-only buttons and actions
- Update focus states from focus-visible to focus for consistency
- Add disabled:cursor-not-allowed for disabled button states
- Improve keyboard navigation with proper focus indicators
Components updated:
- BottomNav: navigation buttons with aria-labels
- Scanner: try again, zoom, word selection, cancel buttons
- ItemComparisonModal: skip and update action buttons
- ConfirmationModal: close, cancel, delete buttons with input focus
- AIOnboarding: all mode toggles, camera, upload, capture, edit, delete buttons
- Plus interactive cards and list items
This ensures WCAG AA compliance for keyboard navigation and visual feedback.
New Component: ItemComparisonModal.tsx
- Shows existing vs new item side-by-side
- Highlights fields that are different (in yellow)
- Options to Update item or Skip (local-only save)
- Shows existing item ID and comparison details
Backend Changes:
- Updated error message to say 'Part Number' not 'barcode'
- 409 response includes existing item data for comparison
- Clear, user-friendly conflict messaging
Frontend Changes:
- New state for comparison modal (newItem, existingItem, existingId)
- handleOnboardingComplete() shows modal on 409 conflict
- handleComparisonUpdate() calls updateItem() API
- handleComparisonSkip() saves locally without syncing
- Better error handling distinguishes 409 from other failures
Workflow:
1. User imports item with Part Number that already exists
2. System shows comparison modal
3. User can:
- Update (merges new data into existing)
- Skip (saves locally, doesn't sync to cloud)
