/* ================================================
   blog.css — استایل اختصاصی وبلاگ نری‌گوله
   Scope: فقط blog.php و blog-post.php را استایل می‌دهد.
   از متغیرهای رنگ موجود در style.css استفاده می‌کند (با مقدار
   پیش‌فرض/fallback) تا با پوسته کلی سایت هماهنگ باشد، بدون اینکه
   هیچ فایل CSS دیگری تغییر کند.

   ردیف تغییرات (UI/UX پابلیک وبلاگ):
   - تایپوگرافی و ریتم عمودی بهتر برای مقاله‌های طولانی
   - سلسله‌مراتب بصری قوی‌تر (بج دسته‌بندی، لید، متادیتا)
   - رندر بهتر heading/list/quote/تصویر داخل متن
   - کارت‌های آرشیو با هویت بصری یکدست‌تر
   - موبایل‌فرست و راست‌به‌چپ
