Replace native window.confirm() dialogs with branded ConfirmationModal component
for all delete operations (users, categories). Implements progressive disclosure
for high-risk operations and requires confirmation text input for deletions with
100+ affected items.
Features:
- ConfirmationModal component with dynamic risk levels (low/medium/high)
- High-risk operations (100+ affected items) require 'DELETE' text confirmation
- Clear consequence messaging with affected item counts
- Loading state during deletion with visual feedback
- Full keyboard accessibility (Esc to cancel, Enter to confirm)
- Proper focus management and ARIA labels
Affected:
- AdminOverlay: Delete user and category now use ConfirmationModal
- New: ConfirmationModal.tsx component
Design: Matches CreateUserModal aesthetic (clean, minimal) with rose-500
accent for danger context. Progressive disclosure shows additional warnings
only for high-risk operations.
Build: Passes with zero errors.
Accessibility:
- Add focus-visible indicators to all interactive elements (buttons, inputs)
- Create accessible CreateUserModal to replace window.prompt()
- Add aria-labels to icon buttons for screen readers
Colors & Theming:
- Move primary color to CSS variable (--primary)
- Remove hard-coded #3b82f6 from tailwind config
- Clean up color consistency across theme
UX:
- Replace prompt-based user creation with proper modal form
- Implement inline field validation with error messages
- Add loading state during form submission
- Improve visual hierarchy and spacing
Performance:
- Remove bootstrap-icons dependency (duplicate with lucide-react)
Design:
- Reduce backdrop-blur overuse (remove from overlay scrim, StatCard)
- Improve AdminOverlay responsive design
- Fix null type error in AIOnboarding.tsx line 352: img src attribute
- Fix similar issue in Scanner.tsx line 237: capturedImage null handling
- Use '|| undefined' pattern to satisfy React 19/Next.js 15 type requirements
- Both components now properly handle null/undefined image states
