/* ============================================================
   SHARED SITE CHROME
   One consistent nav bar + footer wraps both students' original
   dashboards so the merged project reads as a single academic site.
   Deliberately independent of each page's own theme variables, so it
   looks identical whether the page underneath is Mahdiat's light/dark
   storytelling page or Rabeta's fixed dark dashboard.
