   ░░  HUB — المنظومة القيادية (صفحة الحوكمة)  ░░
   أسلوب تقارير المؤسسات: خطوط شعرية، مساحات واسعة، لون ذهبي واحد.
   السلسلة C→P من اليسار، ثم مجلس الخبراء، ثم طبقة القيادة كمخطط
   هرمي (المجلس ← المكتبان ← قادة المسارات)، ثم أرقام المنظومة.
   الأسماء والصور من GOVERNANCE_MEMBERS في governance.js.
   الفاتح أساس القسم، والداكن للإبراز (لوحة ابتكار القيمة، المجلس)
   وللتمرير (مراحل السلسلة).
