/* ==========================================================================
   IRONITT v2 — Communication (first slice: the conversation frame)
   --------------------------------------------------------------------------
   Owns the frame every conversation shares — the channel / whisper header,
   the chat column and the composer — and, on desktop, hands navigation to
   the shell's chats column (css/v2/shell.css, js/shell.js).

   Flat, like the v3 design: the header is a bar with a hairline under it,
   not a card floating over the messages, and the composer is one round
   field. Messages, voice, friends and posts keep their legacy styling for
   now (later slices).
   ========================================================================== */

/* ---- Desktop: the chats column is the navigator ----------------------- */
/* While the chats column is open it lists every whisper, Notes and the
   nest's channels, and the rail lists the nests; the view's own strips
   would only repeat them. Collapsed (or too narrow for the column) they
   come back, and so does the section bar. */
