🐛 Fixed Authentication Problems:
- Removed hardcoded mock admin user from collection detail page
- Removed hardcoded mock user from collections page
- Created proper useAuth hook to get current authenticated user
- Added proper authentication checks and redirects
🔧 Authentication Flow Fixes:
- Collection detail page now uses actual logged-in user (Alice, Bob, etc.)
- Proper permission checks based on real user identity
- Edit/Delete buttons now show correctly based on actual ownership
- Authentication loading states handled properly
🛠️ Technical Improvements:
- Created lib/use-auth.js hook for consistent auth handling
- Added auth loading states to prevent flash of wrong content
- Proper redirects to login page when not authenticated
- Fixed token retrieval from localStorage ('auth_token')
✅ User Experience:
- Alice and Bob now see their own collections correctly
- Edit/Delete permissions work based on actual collection ownership
- No more authentication errors when editing owned collections
- Consistent user identity across all pages
The authentication system now works correctly with the demo users! 🎯
