1/**

2 * Frameless windows on Windows/Linux. Electron 0.1.0 used `titleBarStyle: hidden` with a

3 * native `titleBarOverlay` (min/max/close drawn by Chromium in the top-right 40 px).

4 * Tauri has no overlay, so the same area gets three equivalent buttons here, and the

5 * existing drag regions keep working through a Core command.
