// The tray's context menu, on the shell's own slab.

// Quickshell can hand a StatusNotifier menu straight to Qt's platform menu
// implementation, but that draws a stock widget popup — square corners, system
// palette, no lean — hanging off the corner of a shell that has none of those
// things. This walks the menu with QsMenuOpener instead and draws it as a
// P5Panel, so a right click on a tray icon produces the same object language as
// everything else on the rail.
//
// Dismissal is a Hyprland focus grab: click anywhere outside and the compositor
// tells us to close.
