/* ═══ Degree Advisor — site pages around the homepage ═══════════════════
   Shared by the pages a visitor reaches from the homepage on the way to
   sign-in: universities.html (find your university), university.html
   (/universities/<slug>) and request-access.html.

   The homepage (index.html) is the visual source of truth: the tokens,
   nav, buttons and motion below are copied from it unchanged. If the
   homepage changes, update this file to match — don't add a parallel
   system here. Page-specific layout stays in each page's own <style>.  */
