/**
 * css/seo.css — استایل بلوک‌های محتوای سئو
 * ---------------------------------------------------------------------
 * این بلوک‌ها همان محتوای SSR داخل هیرو‌ی هر نما هستند (inc/views/*.php) که
 * پیش از boot جاوااسکریپت برای خزنده‌ها/کاربر بدون JS رندر می‌شوند. آخرین
 * لایه‌ی cascade است (بعد از auth.css) و فقط از توکن‌های رنگی/فونت موجود در
 * base.css استفاده می‌کند — رنگ یا فونت جدید تعریف نمی‌شود.
 *
 * بلوک‌ها:
 *   .seo-intro           — هیروی محتوای SSR هر صفحه (H1/H2/پاراگراف‌ها)
 *   .seo-links           — لیست پییل‌دار لینک‌های داخلی
 *   .seo-faq             — پرسش‌های متداول قابل مشاهده (FAQPage)
 *   .seo-regions         — شبکهٔ مناطق ۱/۲/۳ کنکور
 *   .seo-tracks          — شبکهٔ گروه‌های آزمایشی
 *   .seo-related         — لیست صفحات مرتبط
 *   .seo-glossary        — واژه‌نامهٔ کلمات کلیدی
