   پربازدیدترین مطالب — اصلاح اختصاصی دسکتاپ
   ---------------------------------------------------------
   این override فقط برای .topic-block--trending است.
   هیچ‌یک از بلوک‌های دیگر صفحه در این بخش تغییر نمی‌کنند.

   • اسکرول عمودی فهرست سمت راست حفظ می‌شود.
   • تصویر اصلی سمت چپ و فهرست سمت راست دقیقاً هم‌ارتفاع هستند.
   • ارتفاع دسکتاپ از clamp(260px, 40vh, 420px)
     به clamp(130px, 20vh, 210px) کاهش می‌یابد.
   • ساختار و رفتار اسلایدر حفظ می‌شود.
