   Escenario oscuro: la escalera de profundos baja monótona desde --brand.

   Scroll nativo: nada se fija ni se ata al scroll. Las entradas son
   transiciones de CSS que site.js dispara al entrar cada sección en
   pantalla (.rv-pend -> .rv-in). El estado por defecto es el final:
   sin JS, o con movimiento reducido, todo se ve desde el principio.

   Compatibilidad: navegadores de los últimos ~5 años (Chrome/Edge 90+,
   Firefox 90+, Safari/iOS 15+, Samsung Internet 15+). Las unidades svh,
   overflow: clip y <dialog> llevan su reemplazo para los más viejos.
