* The load-bearing rule in this file is that nothing here touches |
| 5 |
* `.os-area`. The desktop has one work-area rectangle now |
| 6 |
* (`src/work-area/index.ts`, carved out of the area by the dock), |
| 7 |
* and it stays useful only while few things carve it; a notch that |
| 8 |
* reserved height would be a second claimant on the top edge for |
| 9 |
* the sake of a pill a window may cover. It floats, and it gets out |
| 10 |
* of the way instead. |
| 11 |
* |
| 12 |
* Getting out of the way is also what the stacking order says: the |
| 13 |
* notch is on the desk, under the window layer, so a window reaching |
| 14 |
* the top edge covers the pill instead of the pill hanging over it. |
