/* ==========================================================================
   IRONITT v2 — the voice / call stage
   --------------------------------------------------------------------------
   A nest's voice channel and a whisper call share one stage
   (js/communication.js + js/webrtc.js): a title with its state, the tiles,
   one row of round controls, and the pieces around them — the permission
   card shown before the first join, the music player, the chat that slides
   over the stage, and the small "back to call" chip.

   The stage is in the page, so only what floats over it carries a shadow
   (the chat overlay, the call chip, the jump buttons on video). Speaking is
   a plain accent ring, not a glow; nothing pulses forever.
   Chrome drawn ON video (labels, pin/fullscreen, quality bars) keeps its own
   black plate and white text: the pixels under it are camera content, not a
   themed surface.
   JS contracts kept: .active on .audio-btn and .call-tile-pin; .is-speaking
   on .call-tile; data-layout on .call-stage; .is-open / .is-dragging on the
   chat overlay; .off on .call-perms-toggle; .active on level segments;
   .is-playing / .is-parked on the music player.
