/* =========================================================
   الدالة — النسخة الثانية "Aurora" — نظام تصميم مختلف بالكامل عن V1
   الفكرة: بدل الطابع التقني الداكن (graph paper + f(x))، هذي النسخة
   تعتمد لوحة فاتحة زجاجية (glassmorphism) مع سحابة ألوان متدرجة (aurora
   mesh) تتحرك ببطء بالخلفية، وبطاقات زجاجية عائمة، وخط عرض جريء،
   وعنصر التوقيع: أقواس الشعار البرمجية `< >` تتحول لعنصر انتقال حقيقي
   بين الصفحات (تنغلق/تنفتح مع كل تنقل).
