## Template-Level Protection ✅

Buttons and links are hidden when permissions are denied:
- "Add New Client" button - ✅ Hidden in multiple templates
- Template tag `has_permission` available for any button/link

## Enforcement Strategy

1. **Server-Side (Primary)**: Every view function checks permissions at the BEGINNING, before any processing
2. **Client-Side (Secondary)**: Templates hide UI elements when permissions are denied
3. **Error Messages**: Clear, user-friendly error messages when access is denied
4. **Redirects**: Appropriate redirects to safe pages (dashboard, list pages)

## Testing

All permissions are now enforced. To verify:
1. Create a test user
2. Uncheck specific permissions in `simplified_user_permissions.html`
3. Attempt to access the corresponding feature
4. Verify access is denied and error message is shown
