/*
   Scroll-reveal animations are intentionally DISABLED for SEO.

   Background: opacity:0-by-default with IntersectionObserver caused
   Yandex/Googlebot to see invisible content (search engines don't
   scroll the page during render), which got pages penalised as
   "hidden text" / "thin content" — the site was deindexed for ~6
   months.

   Content is now visible immediately. The class names and data-delay
   attributes are kept on the markup so we can re-enable animations
   in the future via JS-only without re-touching every HTML page.

   The header/footer scroll effects, the homepage demo panel and
   smooth anchor scrolling continue to work — they don't hide content.
