/*
 * ====================
 * ملخص التحسينات
 * ====================
 * 
 * تم تطبيق نمط التصميم العلمي على جميع صفحات المنصة، وتشمل:
 * 
 * 1. صفحات الامتحانات:
 *    - صفحة عرض الامتحانات المتاحة
 *    - صفحة بدء الامتحان
 *    - صفحة الامتحان أثناء التنفيذ
 *    - صفحة نتائج الامتحان
 * 
 * 2. تحسينات بصرية:
 *    - إضافة خلفيات بصرية وأشكال متحركة
 *    - استخدام الألوان العلمية (الفيزياء، الكيمياء، الأحياء)
 *    - تحسين عناصر واجهة المستخدم بتأثيرات حركية
 *    - إضافة أيقونات وتفاصيل تناسب المحتوى العلمي
 *    - توحيد الأزرار والعناصر التفاعلية
 * 
 * 3. تجربة مستخدم محسنة:
 *    - تصميم متجاوب للهواتف والأجهزة المختلفة
 *    - تحسين عرض الأسئلة والإجابات في الامتحانات
 *    - تحسين عرض النتائج بطريقة أكثر وضوحاً
 *    - إضافة مؤثرات انتقالية سلسة بين العناصر
 *    - توحيد أنماط العرض عبر صفحات المنصة
