/* ============================================================
   BKRTC LMS + Online Examination Portal — Design System
   ------------------------------------------------------------
   Builds on top of the site's existing --navy/--saffron/--gray
   tokens (assets/css/style.css) so it stays visually part of the
   same portal, while giving the learning/exam areas their own
   identity:
     - LMS section reads in navy + saffron + gold (certificate feel)
     - Exam Portal section reads in teal (visually distinct "mode")
   Signature element: the "medallion" progress ring — a gold-rimmed
   circular badge that fills in as lessons/exams are completed,
   echoing BKRTC's own certificate & award visual language instead
   of a generic progress bar.
