   شرح تصميم شاشة الطلاب
   1. students-page: حاوية الصفحة وتحديد اتجاه العرض RTL.
   2. students-header: عنوان الشاشة وأزرار الإجراءات.
   3. students-card: بطاقات المحتوى.
   4. students-grid: توزيع حقول الإدخال على عمودين.
   5. @media: تغيير توزيع الحقول لتناسب الموبايل والتابلت.
   قاعدة مهمة: لا تضع وظائف الحفظ داخل CSS؛ وظيفته الشكل فقط.

   إضافات تصميم شاشة التعديل — شرح للمبتدئين:
   .students-mode: شارة صغيرة توضّح هل نضيف أم نعدّل.
   .students-edit: زر داخل صف الجدول، يختلف عن زر حفظ النموذج.
   @media: يجعل الأزرار مناسبة للشاشات الصغيرة.
