/* =====================================================================
   سازگاری Bootstrap 4 → Bootstrap 5 (سمت کاربر)
   سایت حالا فقط Bootstrap 5.3 (RTL) را بار می‌کند. کلاس‌های قدیمی Bootstrap 4
   که هنوز در صفحه‌ها/HTML تولیدی سرور استفاده می‌شوند این‌جا تعریف شده‌اند
   تا ظاهر صفحه‌ها به هم نریزد. کد جدید باید از کلاس‌های Bootstrap 5 استفاده کند.
   (ml/mr/pl/pr/float/text-left/right همان معنای فیزیکی Bootstrap 4 را دارند)
