/* Visible por defecto; JS agrega .reveal--armed solo si puede observar y
   volver a revelar el contenido (así un script bloqueado/lento nunca deja
   nada invisible para siempre). El retraso escalonado lo fija JS por
   elemento vía --reveal-delay para que las grillas entren en cascada.

   Usa `animation` (no `transition`) a propósito: varios componentes
   (`.category-card`, `.testimonial-card`, etc.) definen su propia
   `transition` para sus hovers en hojas de estilo que cargan después de
   esta — si el reveal también usara `transition`, esa declaración
   posterior ganaría la cascada completa (incluida `opacity`) y el fade-in
   se rompería en silencio. `animation` es una propiedad distinta que
   nunca choca con `transition`, así que conviven sin importar el orden
   de carga de los CSS. */
