/* ── Notification centre — bell dropdown panel ──────────────────────────────
   The bell (fragments/notifications/bell.html) is a Bootstrap dropdown shared by both
   chromes; the menu drops down from under the topbar (Popper-anchored to the bell).
   Rows are mini-cards: a colour-chip icon (accent per NotificationTopic.Accent), a left
   accent bar for unread, and a two-line clamped body. Forward-compatible with Etap 2
   grouping — .notif-chip__count renders the digest/coalesce counter with no layout change. */
/* Qualified as .dropdown-menu.notif-menu (specificity 0,2,0) so these win over Bootstrap's
   `.dropdown-menu[data-bs-popper] { top:100%; left:0; margin-top:.125rem }` (same 0,2,0, but app.css
   loads after Bootstrap → later source wins the tie). data-bs-display="static" keeps Bootstrap's
   static drop (top:100% / right:0 under the bell on desktop) with no Popper inline transform. */
