// OpenLogi Frontmost Window — GNOME Shell extension.
//
// Exports a tiny D-Bus service that returns the WM_CLASS of the currently
// focused window. OpenLogi's `gnome_shell` frontmost backend polls this to
// drive per-app mouse-profile switching on GNOME Wayland, where the focused
// window is otherwise not visible to ordinary clients.
//
// It reads only `global.display.focus_window.get_wm_class()` — no titles, no
// window contents, no input. ESM module style; targets GNOME Shell 45+.
