/* ─────────────────────────────────────────────────────────────────────────
   PipChat! Web — Notifications: the nav bell + popover, and the /notifications
   inbox.

   One rule carries the look: every notification has a --nt tone taken from its
   own type, and the icon tile, the kind label, the unread wash and the left
   rail all inherit it. A list of forty reads as a coloured index rather than
   forty identical grey rows.

   Reminder (see app.css): icons are inline <svg> with a viewBox and no
   width/height, so every component here declares its own svg size.
