/* ============================================================
   GrammarBound — homepage deadline urgency banner (FEAT)
   A thin strip that sits between the navy hero and the first
   light section. Rotates the action-required admissions
   deadlines and ramps its tone as each one nears.

   Link AFTER scheme.css on index.html:
     <link rel="stylesheet" href="/gb-deadline-banner.css" />
   Behaviour lives in /gb-deadline-banner.js.

   Colours stay inside the navy + brass system; the final two
   tiers borrow the map's warm "score" terracotta (#9A3412 /
   #C2724E) rather than a pure red.
   ============================================================ */

/* CLS: reserve the strip's height before the (async) JS insert, so filling it
   doesn't shift the page. gb-deadline-banner.js locks this to the exact rendered
   height once mounted, and collapses the slot if there's no banner to show. */
