/* SERVICE HERO 16 - SCROLL, LE FILM SUR SON RAIL
   La version `scroll` de service-hero-5 : l'image à gauche avec deux
   chiffres en surimpression, le texte à droite (fil d'Ariane, badge, H1,
   description, prestations du service, boutons). L'image devient le film du
   service, bordé d'un rail dont les stations s'allument étape après étape ;
   le récit se déroule à droite et s'achève sur les prestations et les
   boutons.

   Mécanique partagée : heros/main.css et heros/main.js (`data-hero-scroll`).
   Pas de header transparent : la scène commence sous le header.

   Fonds réels : le blanc du panneau de texte (texte --black) ; sur l'image,
   le rail (blanc, sur un voile) et les cartes blanches des chiffres. */
