/** |
| 2 |
* Simple toolbar bootstrap. |
| 3 |
* |
| 4 |
* Vanilla JS bound to the bar that `Frontend::render()` writes at |
| 5 |
* `wp_body_open`. Three integrations: |
| 6 |
* |
| 7 |
* - "AI Agent" button → drives the Extendify Agent's mounted |
| 8 |
* admin-bar button (the bar is hidden via CSS but stays in the |
| 9 |
* DOM so the Agent's React code can still target it). |
| 10 |
* - "Quick Edit" toggle → dispatches a custom event the Quick Edit |
| 11 |
* bootstrap listens for. Aria-checked mirrors the |
| 12 |
* `extendify-quick-edit-on` class on `<html>` so the toggle |
| 13 |
* reflects state changes from any source (admin-bar pill, |
| 14 |
* chat-input "Select" button, etc.). |
| 15 |
* - When the Agent sidebar opens, the toolbar slides next to it |
| 16 |
* so the rounded-frame layout matches what the Agent does to |
| 17 |
* the core admin bar. |
