/* ==========================================================================
   Announcement bell -- header/nav notification icon + dropdown.
   Loaded site-wide (csstemplate.jsp) since the bell appears in both
   header.jsp and profile-header.jsp, desktop nav and mobile sticky bar.
   Shares the --lms-navy / --lms-ink / --lms-line tokens used by the
   redesigned "lms-" pages (see online-course-enhancements.css) but defines
   its own copies so it renders correctly even on pages that don't opt into
   that stylesheet (e.g. home.html).
