/* ── "…and you were named in it" ───────────────────────────────────────────────
   A MODIFIER ON THE UNREAD INDICATOR, never a second element beside it. Being
   mentioned is a property of unread — the server only ever flags a session it
   has already returned as unread — so a separate badge would be a second thing
   to clear, able to disagree with the first about whether you have caught up.

   It reads as a mention, not as a colour: a red "@" in a small circle. Red is
   what a message shows your own name in (`.mention-name--self`), so the list
   and the transcript use the same cue. The glyph is drawn by CSS (the node
   stays empty), and `title` / `aria-label` say it in words. */
