/* ==========================================================================
   قسمة ونصيب — مفهوم "زقاق النيون" (Concept v4)
   عالم بصري مختلف كلياً عن المفهومين السابقين (سجل هادئ / شبكة سويسرية
   صامتة): واجهة مبنى ليلية مليئة بلافتات نيون متوهجة، انعكاسات على رصيف
   مبلّل، ميلان ثلاثي الأبعاد حقيقي، وحركة "الوميض قبل الثبات" بدل الكشف
   الهادئ. نفس رموز الألوان الكهربائية من app/src/theme.ts بالضبط، بس
   مستخدمة بكامل تشبّعها كنيون حقيقي لا كلمسة مقيّدة.
