   9. Scroll reveal
   Removed for now — on a single-page reading site, fade-in just produces
   blank gaps when sections are below the fold. The CSS lives below in case
   it's useful later; the script no longer adds the .reveal class.

  opacity: 0;
  transform: translateY(8px);
  transition: opacity var(--duration) var(--ease), transform var(--duration) var(--ease);
  will-change: opacity, transform;

  opacity: 1;
  transform: translateY(0);
}

@media (prefers-reduced-motion: reduce) {
