   AV SYSTEMS — CAPA DE MOVIMIENTO (SCROLL & REVEAL)
   Se carga DESPUÉS de landing.css. Es aditiva: no reescribe el sistema
   visual, solo añade el comportamiento al hacer scroll.

   Cómo funciona el ocultado:
     - Todo lo que se anima lleva  data-reveal
     - El estado OCULTO se declara siempre con  .js-motion ...:not(.is-in)
       · .js-motion  → sin JavaScript no se oculta nada
       · :not(.is-in) → al revelarse, la regla deja de aplicar y valen los
         valores por defecto. Así no hay peleas de especificidad.
     - El estado visible no necesita reglas propias.

   Curva base: ease-out largo, sin rebotes (el gesto de Apple).
   ========================================================================== */

   0. ARREGLO BASE: que `position: sticky` pueda funcionar

   landing.css pone `overflow-x: hidden` en html y body para evitar el
   scroll lateral. Efecto secundario: eso convierte al body en su propio
   contenedor de scroll y ANULA `position: sticky` en toda la página
   (la baraja de servicios dejaría de fijarse y quedaría un hueco negro).

   `overflow-x: clip` recorta exactamente igual pero NO crea contenedor de
   scroll, así que sticky sigue vivo. Va dentro de @supports: si el
   navegador no lo entiende, se queda con el `hidden` de antes y la baraja
   no se enciende (lo comprueba landing-motion.js).
