The Preferences window's availability probe (added to surface missing GStreamer deps in-UI) reused loadGstreamerModules(), which also checks for Cogl. Cogl is Mutter's private library — its typelib is only reachable from inside the actual gnome-shell process (which gets a private GI search path), never from the separate, plain-GTK4 Preferences process. So the check always failed there with "Requiring Cogl ... not found" even when live wallpapers were working correctly in the real shell process, as confirmed by a user report where the extension's own log showed live wallpaper playback starting cleanly while Preferences simultaneously claimed GStreamer was missing. Split into loadGstreamerModules() (Gst+GstApp+Cogl, used only by liveWallpaper.js in the shell process) and a new lighter checkGstreamerBaseAvailable() (Gst+GstApp only) for prefs.js, with a note in the UI that a clean check there isn't a full guarantee since the private half can't be verified from that process.
