| 7 |
* 1. Logged-out users are bounced through `wp-login.php` with a |
| 8 |
* redirect back to `/desktop-mode/`. |
| 9 |
* 2. Logged-in users with basic admin-read capability have the |
| 10 |
* `desktop_mode_mode` user-meta toggle auto-enabled on first visit, |
| 11 |
* then are forwarded into `wp-admin` at whichever window was |
| 12 |
* last focused in their saved session (or the dashboard as |
| 13 |
* fallback). |
| 14 |
* |
| 15 |
* The URL is served virtually (no rewrite rules, no `.htaccess` |
| 16 |
* surgery) by intercepting `parse_request` before WordPress routes the |
| 17 |
* URL to 404. This keeps the plugin drop-in. |
