* Multi-tab native windows are a sister-to-the-window |

* registration: a tab is owned by some window id and its content |
| 7 |
* is wrapped in `<wpd-tabpanel>` automatically by the shell. The |
| 8 |
* MAIN_TAB constant reserves the `'main'` value for the window's |
| 9 |
* own `template` callback so plugins can't accidentally collide |
| 10 |
* with the built-in main pane. |
| 11 |
* |
| 12 |
* Extracted from `components.php` during the architecture-0.8.1 |
| 13 |
* PHP slicing (phase 6). |

| 37 |
* `template` renders as the first tab (labelled by `main_tab_label` |
