/* =================================================================
   exam-countdown.css — the "Exam dates" card and chips
   Rendered by assets/js/exam-countdown.js from upcoming_exams:
     .mtm-cd-list   the card in an exam hub's side column
     .mtm-cd-chip   one line of chips under a subject page's title and on
                    the signed-in home page
   The markup ships a static fallback (a link to the exam calendar) that
   occupies the same space, so nothing moves when the dates arrive.
   Every colour is a token with a fallback, so pages that do not load
   main.css (subject pages) and dark mode both work.
