/* ============================================================
   БЛОК «Каталоги PDF» (lux-docs).
   Грид карток: картинка + назва + кнопки «Переглянути» (поп-ап
   із превью PDF) і «Завантажити». Десктоп 4/3/2 колонки (клас
   --2/--3/--4), мобільний — завжди 2. Типографіка через clamp.
   Лінія зліва — глобальна (.lux-docs::before у style.css).
