+// Earpiece <-> speaker toggle for calls. Registered by cap sync as a real Capacitor plugin package, so it
+// shows up as window.Capacitor.Plugins.AudioRoute (an app-embedded class gets stripped in release builds).
+//
+// WHY THIS SHAPE (earlier version left the earpiece silent):
+//  * The category is configured WITHOUT .defaultToSpeaker, so overrideOutputAudioPort(.none) reliably means
+//    the earpiece/receiver. WITH .defaultToSpeaker, .none falls back to the loudspeaker and the earpiece
+//    never receives audio.
+//  * setSpeaker flips ONLY overrideOutputAudioPort. It must NOT re-setCategory/setActive mid-call: doing so
+//    tears down the audio unit WebKit's WebRTC engine is actively using and leaves the earpiece route silent
+//    (forcing .speaker is a strong enough override to survive it, which is why only speaker "worked").
+//  * WebKit reconfigures the shared AVAudioSession when call audio starts (and on headset plug/unplug), which
+//    would clobber our choice — so we observe routeChangeNotification and re-assert the desired port. That
+//    also removes the "call starts on speaker then drops to silence" flicker.
