   تمكَّن — FINAL OVERRIDE CSS v2
   يُحمَّل آخراً في HTML — أعلى أولوية مطلقة
   Sprint 18 — Clean Unified System
   
   تشخيص مشاكل sprints السابقة:
   1. pv2-card: تعريفات متضاربة (column ثم row) في clean-uiux-fix.css
   2. pv2-icon: 6+ تعريفات متضاربة
   3. type-card-head: CSS موجود لكن غير كامل
   4. activity-card: padding متضارب
   5. pv2-desc: display:none على mobile في main.css (مقصود لكن يحتاج تعديل)
