/* ============================================================
   Examplar homepage v2 - "Control Room"
   Replaces homepage-styles.css + index-inline.css on index.html.
   Loads AFTER the legacy shared sheets (style-new, multi-exam,
   modern-enhancements, exam-enhancements), which keep powering the
   inline exam/results screens; later rules here win the landing
   surfaces. Every class generated by homepage.js is covered.
