/* 8i. MOVIMIENTO (Home): entrada del hero, aparición al scroll y hover
   Estrategia sin parpadeo (FOUC) y progresiva:
   - Hero: animación CSS pura al cargar (una vez), solo si el usuario no pidió
     reducir movimiento. Sin JS no hace falta nada: la animación termina visible.
   - Scroll: UNA sola fuente de verdad, html.js-motion. motion-init.js (en
     <head>, antes del primer pintado) la agrega solo si hay
     IntersectionObserver y no se pidió reducir movimiento; reveal.js revela
     los [data-reveal] al entrar al viewport. Si reveal.js no inicia en 4 s,
     motion-init.js quita js-motion y todo queda visible; si falla, igual.
     Sin JS no existe js-motion. El CSS no repite la condición de "reducir
     movimiento": así CSS y JS nunca pueden discrepar.
   - Se animan opacity y las propiedades individuales translate/scale (no
     chocan con los transform propios de cada elemento).
