   BARAEM GRADEFLOW — DRILL-DOWN

   The page a chart click opens. It has to answer "what exactly am I looking at?"
   before it answers anything else, so the context block and the breadcrumbs sit
   above the figures and stay put while the numbers change.

   Same system as everything else: deep green, slate neutrals, hairline rules,
   generous whitespace, state colour only where it means something.
