   🎯 الإصلاح النهائي — التجاوز الأفقي
   ────────────────────────────────────────
   ثلاثة عناصر تمدّ منطقة التمرير:

   1) .navbar::before  وميض عند left:-100%
      في LTR يُقصّ بصمت، وفي RTL اليسار هو
      اتجاه الفائض فيُحسب كاملاً.

   2) .mobile-nav  عند right:-100% وهي fixed.
      العناصر الثابتة لا تنحصر بـoverflow
      على html أو body — قاعدة في المتصفحات.
      الحلّ: transform بدل right، فالتحويلات
      لا تدخل في حساب مساحة التمرير.

   3) <select> يرث عرضاً أدنى من أطول خياره،
      و 1fr تعني minmax(auto,1fr) فيرفض العمود
      أن يصغر — وهذا سبب إزاحة الخطوة الثانية.
