   AI-ENG MART - site.css : هوية موقع نظام AI-ENG للسوبر ماركت (قيد التطوير)
   EN: Site styles - the AI-ENG family (black, gold, Reem Kufi / Cairo) with a fresh grocery-green accent for MART highlights
   ----------------------------------------------------------------------------
   - المظهران: data-theme="dark" (الافتراضي) و"light" ، والألوان كلها متغيرات هنا فقط.
   - الذهبي = الهوية والأزرار و«مخطط» ، الأخضر الطازج (--fresh) = لمسات MART فقط ،
     الأخضر (--green) = متاح اليوم (AI-ENG Retail) ، الأحمر = خطأ. لا تدرّج لوني للزينة.
   - الحركة تتوقف كلها مع «تقليل الحركة» ، والعرض 375 بكسل بلا تمرير أفقي.
