/* Auto-rejoin without a user gesture works on desktop (browsers
* grant audio engagement after first interaction with the origin)
* but breaks mobile listener audio: Firefox Android requires the
* silent-oscillator wake in primeAudioOnGesture to actually start
* the AudioContext render thread, and primeAudioOnGesture only
* runs inside the btn-enter click handler. Auto-rejoin that
* bypasses the click → audioCtx stays suspended → MediaStream-
* Source attaches silently → no audio.
*
* UA-gated: desktop preserves the zero-click rejoin convenience;
* mobile pre-fills the code + asks for one tap on enter so the
* gesture window opens and audio actually plays. Fox 2026-06-04
* chose this trade after the AudioContext-suspended telemetry. */
