/* IMPORTANTE: overflow-x:hidden en html/body rompe position:sticky en muchos
   navegadores (Safari, y a veces Chrome/Firefox) porque convierte body/html en
   un "scroll container" que ya no es el viewport real. Las secciones full-bleed
   ya controlan su propio overflow localmente (.hero, .cine-section, .marquee,
   .assembly-sticky, etc.), así que no hace falta este corte a nivel global. */
