// ScopedMenuBarLock uses an AppKit API to lock the menu bar in its current
// state (visible/hidden). Useful to temporarily keep the menu bar visible
// after appearing when the user moved the mouse to the top of the screen, or
// to temporarily prevent the menu bar from showing automatically.
// ScopedMenuBarLock helps enforce that lock/unlock calls are balanced.
