/* ══════════════════════════════════════════════
   ACTINUANCE — Accueil : section « Quatre expertises »
   Défilement horizontal épinglé : un grand panneau par expertise,
   avec ce qu'elle couvre et ses offres (liens vers chaque offre).
   Profondeur : le panneau qui arrive grandit, celui qui part recule,
   le grand numéro et le halo défilent à une autre vitesse.
   Les offres de chaque expertise sont mises en avant en tuiles.
   Chargée après ax.css.
