/* Categoría ISO: recorrido de las normas 2026 con scroll telling (2026-10-22). Tres capítulos con fondo propio, cada uno con
   un escenario fijo (sticky) que se mueve al ritmo del scroll: el ciclo de la norma (azul noche), el emulador con Envases del
   Bajío (claro) y las portadas con el precio del paquete (azul SAR). Lo mueve assets/js/sar-iso-recorrido.js con --p (0 a 1).
   Botón flotante «Adquirir» del paquete ISO (.sar-iso-buy). Sin JS no se ve (data-sar-cat-only lo deja oculto). */
