/* ==========================================================================
   Announcements chrome — the topbar bell's unread badge and the
   per-section what's-new strip. Loaded on every page from
   includes/assets/css.html; the archive page's own styles live in
   whats-new.css, loaded only there.

   Every color reads a token; the one literal white is a label on a
   solid accent, which is theme-invariant (see avatar.css).
