| 4 | // protects: the card's render condition and the toggle's pressed state must |
| 5 | // never diverge). Two layers: |
| 6 | // 1. Truth-table over resolveLauncherCardState — every combination of |
| 7 | // spaceMode × dismissed. The card is independent of the dock panel's |
| 8 | // open state: the panel has its own toggle. |
| 9 | // 2. Source contracts — App must drive the toggle through the shared |
| 10 | // resolver (not inline the condition again), and DockLauncher must keep |
| 11 | // reporting its space-yield mode upward. |
