   ★ هوية «مكتبة المتنبي» — نبيذي عميق مع ذهبي عتيق ★

   نظام «مكتبة أحمد» كحليّ (#16324F). هذا النظام نبيذيّ عمداً كي
   يعرف الكاشير من أول نظرة أيّ محلّ فتح، فلا يبيع على المحل الخطأ.

   كل ألوان النظام تُشتقّ من المتغيّرات أدناه — لتغيير الهوية كلها
   يكفي تعديل هذه الأسطر وحدها، ولا تُلمس بقية الملف.
