   Решили не делать общий scroll-reveal на всю страницу: в разных браузерах
   IntersectionObserver и scroll-события при быстрой прокрутке батчатся
   по-разному, и часть блоков рисковала оставаться невидимой. Вместо этого —
   один аккуратный fade-in при загрузке только для первого экрана (герой),
   чистый CSS, без зависимости от скролла или JS. Остальной контент статичен
   и виден сразу — это надёжнее и не менее эффектно. */
