Problem
The desktop app uses the operating-system window frame, but Windows keeps the compatibility-default light title bar even when the app is dark. This produces a disconnected white frame around the native desktop experience.
Expected behavior
Keep the system-owned title bar and window controls while asking Windows to render its frame for the active app theme. Linux and macOS must continue using their native window-manager decorations.
Acceptance criteria
- The Windows title bar follows dark and light app theme changes.
- Minimize, maximize, close, resize, and system window behavior remain OS-owned.
- Failure to apply an optional DWM visual attribute does not prevent app startup.
- Desktop and Windows package validation pass.
