/* =========================================================
   نظام التصميم: Academic Pillar — Institutional Excellence & Tonal Depth
   مستوحى من Stitch Design System "The Academic Curator"
   
   قواعد أساسية:
   - قاعدة "No-Line": ممنوع border 1px للفصل - نستخدم تغيير الخلفية
   - العمق بالطبقات اللونية لا بالظلال
   - Ghost Border: outline_variant بشفافية 15% فقط عند الضرورة
   - لا نستخدم أسود 100% — دائماً on_surface (#191c1c)
   - شبكة 8px أساسية
