+// The window the bubble lives in.
+//
+// A layer-shell surface on the overlay layer, anchored to the top edge and
+// transparent to input, so it floats above everything the way the island on a
+// phone does and never takes a click or a key from what is under it.
+//
+// On top of that it asks KWin to keep showing it while the screen is locked
+// (kde_lockscreen_overlay_v1). KWin only grants that to programs whose desktop
+// file lists the interface, which the one installed with this does. The
+// request has to be made for every new surface role, before it is mapped, so
+// it is repeated each time the window is shown again.
