/** |
| 3 |
* Desktop OS Settings tab registration APIs. |
| 4 |
* |
| 5 |
* Two entry points, mirroring the command-palette surface |
| 6 |
* ({@see includes/commands.php}): |
| 7 |
* |
| 8 |
* - `openstation_register_settings_tab_script( $handle )` — primary, |
| 9 |
* minimum-ceremony opt-in. Tells the shell: "this enqueued script |
| 10 |
* registers OS Settings tabs; include it in the plugins-changed |
| 11 |
* payload so it gets injected mid-session without a full reload." |
| 12 |
* |
| 13 |
* - `openstation_register_settings_tab( $args )` — optional. Declares |
| 14 |
* tab metadata server-side so the shell can live-unregister tabs on |
| 15 |
* plugin deactivation without the JS having to tag every |
| 16 |
* `registerSettingsTab()` with an `owner`. |
| 17 |
* |
| 18 |
* Both APIs feed `openstation_build_desktop_settings_tab_scripts_payload()` |
| 19 |
* and `openstation_build_desktop_settings_tabs_payload()`, which contribute |
| 20 |
* `serverSettingsTabScripts` and `serverSettingsTabs` to the shell |
| 21 |
* payload in `openstation_build_menu_payload()`. |
| 22 |
* |
| 23 |
* The tab's `render` callback lives JS-side — the PHP layer only |
| 24 |
* ferries identity and metadata. |
| 25 |
* |
