/* ==========================================================================
   IRONITT v2 — Whispers (direct messages)
   --------------------------------------------------------------------------
   The conversation itself: header extras, bubbles, replies, shared posts,
   Notes, the phone's whisper list and the avatar strip shown when the
   chats column is closed. The frame (header bar, composer) is in
   communication.css; the call stage stays with the voice surface.

   Bubbles are the one place colour fills a shape in chat: yours sit on the
   accent's softest step, theirs on the surface fill. Nothing floats here,
   so nothing has a shadow, and nothing animates in on render (re-renders
   would replay it for every bubble).
   JS contracts kept: .own/.other and .cluster-start/.cluster-end on rows;
   .visible on the jump button; .mobile-dm-list-open on .dms-panel;
   .reply-bar is rebuilt by _renderReplyBar for channels and whispers.
