 // 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.
