/*
  نظام تصميم Alsafa Technology — عصريّ، احترافي، ثلاثي اللغة (en/ar/he).

  درسٌ تعليمي مهم هنا: بدل margin-left/margin-right التقليدية، تُستعمل
  "الخصائص المنطقية" (logical properties) — margin-inline-start بدل
  margin-left مثلاً. الفرق: margin-left يبقى "يساراً" دائماً بصريّاً، بينما
  margin-inline-start يعني "بداية السطر" وتنعكس تلقائياً مع اتجاه اللغة —
  فتصميمٌ واحد يعمل صحيحاً في LTR (إنجليزي) وRTL (عربي/عبري) دون أي كودٍ
  مكرّر أو كلاسات rtl./ltr. خاصة. هذا هو سبب عدم وجود أي media query أو
  كلاس مخصّص للعربية/العبرية في هذا الملف كلّه.
