## 🔄 User Workflow Examples

### Admin Workflow:
1. Login at `/login.php`
2. Create new users (with role: user or admin)
3. Add global domains (visible to all users)
4. View all users, domains, shortlinks
5. Manage system settings

### User Workflow:
1. Login at `/user-dashboard/login.php`
2. Go to "Create Shortlinks" tab
3. Select domain (global or own private)
4. Create bulk shortlinks (1-25)
5. View created links in "My Shortlinks" tab
6. Go to "My Domains" tab
7. Add private domain (only visible to this user)
8. Domain auto-added to Cloudflare if enabled
9. Use private domain for shortlinks

### Domain Visibility:
- **Admin adds domain:** `example.com` with `is_global = 1`
  - Visible to: ALL users
- **User adds domain:** `mytest.com` with `user_id = 5`
  - Visible to: Only user ID 5 + admins (via DB)
