   ------------------------------------------------------------
   تنسيقات Workspace تعديل المقالات الموحّد (المرحلة 2A — Skeleton).

   مبادئ:
     - الـ overlay يغطي مساحة الـ <main> فقط، ويحترم الـ sidebar.
     - body.workspace-locked يمنع scroll الخلفية.
     - z-index بين البطاقات العادية (~10-100) و modals النظام (1600+).
     - لا اعتماد على :has() — يعمل في كل المتصفحات الحديثة المدعومة.
     - يعتمد فقط على CSS variables الموجودة في global-ui.css
       (--sidebar-width, --surface, --border, ...).

   ⚠️ لا تنسخ شيئاً من هذا الملف إلى global-ui.css. التنسيق معزول قصداً.
