   - UserSettings interface
   - GeneralSettings interface
   - NotificationSettings interface
   - UserSession interface

7. **API Methods** - Updated `/mnt/data-disk1/georgia/lib/api/georgia-api.ts` (+180 lines)
   - getUserSettings(): Fetch user settings
   - updateUserSettings(settings): Update settings
   - getUserSessions(): Fetch active sessions
   - revokeSession(sessionId): Revoke specific session
   - revokeAllOtherSessions(): Revoke all except current
   - All methods include mock data and TODO comments for backend integration

## Acceptance Criteria Met:

✅ Display current settings (general, notifications, security)
✅ General preferences: timezone, language, date format, number format
✅ Notification toggles: email, push, notification types, frequency
✅ Active sessions table with device info and icons
✅ Revoke individual sessions with confirmation
✅ Revoke all other sessions functionality
✅ Preview of format changes in real-time
✅ Success toasts on save
✅ Error handling throughout
✅ Current session highlighted
✅ Clean, professional UI using Archie-UI components

## Technical Features:

- Proper TypeScript typing throughout
- React hooks for state management
- Form validation and change detection
- Mock API with realistic delays
- Responsive design
- Accessibility considerations
- Security confirmations for session revocation
- Device icon detection (desktop/mobile/tablet)
- Smart time formatting
- Error boundaries and loading states

## Database Integration Ready:

When backend is ready, replace mock implementations with:
```sql
-- Get settings
SELECT * FROM georgia_user_settings WHERE user_id = $1;

-- Get sessions
SELECT * FROM georgia_user_sessions 
WHERE user_id = $1 AND expires_at > NOW() 
ORDER BY last_active DESC;

-- Revoke session
UPDATE georgia_user_sessions 
SET expires_at = NOW() 
WHERE id = $1 AND user_id = $2;

-- Revoke all other sessions
UPDATE georgia_user_sessions 
SET expires_at = NOW() 
WHERE user_id = $1 AND id != $2;
```

## Next Steps:

1. Backend API implementation to replace mock data
2. MFA implementation (marked as "Coming Soon")
3. Additional timezone support if needed
4. Email template preferences
5. More granular notification controls
