   HOME · 1C — Marquee de sectores (banda de scroll infinito)
   Técnica canónica: UN contenedor animado (.marquee__inner) envuelve TRES copias
   estáticas (.marquee__track) y se desplaza -33.333% (1/3) de su ancho total.
   Cada track lleva padding-right IGUAL a su gap interno, de modo que el ancho
   de una copia incluye el hueco que la separa de la siguiente → el bucle es
   continuo, sin salto al reiniciar. Se usan 3 copias (no 2) porque cada copia
   individual (~1145px con los 6 sectores) es más corta que los viewports
   anchos (hasta ~1920px): con solo 2 copias quedaba un hueco visible detrás de
   "Industria" antes de que la copia 1 volviera a entrar. Con 3 copias, el
   colchón de contenido repetido (~3435px) cubre de sobra cualquier viewport
   ancho en todo el ciclo. Las copias 2 y 3 van aria-hidden + inert y con
   <span> (nada interactivo; solo la copia 1 es navegable). Pausa al hover; al
   tabular dentro (focus-within) la animación se ANULA (la banda vuelve a x=0)
   para que el enlace enfocado sea visible.
   Bajo reduced-motion: estática, sin copias duplicadas visibles y sin scroll.
