/* State-based autoplay-block detection: if any audio element has data
* (rs>=2 HAVE_CURRENT_DATA) but stays paused at ct=0, play() either
* silently failed or the pre-blessing wore off when srcObject was
* swapped. The Firefox Android phone hits this consistently: receiver
* decodes audio (level>0 in aud.recv stats) but the <audio> stays
* pa=1 ct=0.00 forever. play()-promise-reject doesn't fire in that
* shape, so a state-based trigger is the only reliable detector.
* Only fire on listener role — speakers/cohosts/hosts get the same
* pre-blessing path but also have an active mic that requires its
* own gesture chain we don't want to disturb. */
