 1. ✅ `GlobalHotkeyManager` service — `Services/GlobalHotkeys.cs`: registers OS-level hotkeys on the window HWND via `RegisterHotKey`/`WM_HOTKEY` (`IHotkeyRegistrar` seam for tests; `RegistrarOverride` mirrors `LayoutPathOverride`). Wired in `MainWindow.OnSourceInitialized`.
 2. ✅ Scene switching hotkeys — F1-F5 stage/transition the five canonical scenes.
