 - TASK 27 — YouTube Chat layer one-per-layout gate (`CanAddYouTubeChat`, AddSource refuses a second) + legacy label heal ("Chat" → "YouTube Chat" on LoadLayout; creator renames untouched; test `ChatLayerGateTests`). Creator's ask: "do the same thing with the YouTube chat layer" + make the Layers row match the (+) picklist.
 - TASK 19/23 status flip — code survey confirmed Control Surface UX fully shipped (thumbnail strip, two-state left panel, right panel gone, transitions, edit gating); map corrected.
 - **TASK 20 step 1 — global hotkeys** (`Services/GlobalHotkeys.cs`, `MainViewModel.HandleHotkey`, `MainWindow.OnSourceInitialized` wiring): F1-F5 canonical scenes, F6 start/end stream, F7 mic mute, F8 desktop mute, F9 TRAX. `IHotkeyRegistrar` seam + `RegistrarOverride`. Test `GlobalHotkeyTests.WmHotkey_StagesScene_And_TogglesMic_And_RevokesOnClose`. Hotkeys validated by creator.
-- **ON-AIR sign** (creator ask): new status light + "ON-AIR" right of REC in the top bar (`OnAirBrush`: gray offline / red public / green private); old left-of-REC hardcoded indicator removed. Test `OnAirSignTests.OnAirBrush_Follows_Offline_Public_And_Private`.
+- **ON-AIR sign** (creator ask): new status light + "ON-AIR" right of REC in the top bar (`OnAirBrush`: gray offline / red public / green private); old left-of-REC hardcoded indicator removed. Labels share one `StatusSignText` style in Controls.xaml (creator dinged inconsistency when ON-AIR text took the status color — labels are neutral, dots carry state). Test `OnAirSignTests.OnAirBrush_Follows_Offline_Public_And_Private`.
 - Suite: 227 total, 226 pass — only failure is the known pre-existing `AudioPipelineTests.Mix_HonorsProviderGains_AndGameMute_KillsTheLoopback`. Build 0 warnings. Docs shipped same-commit.
 - Visual pass on TASK 26/27 validated by creator (2026-08-24).
