   Congrès régional Spéléo & Canyon 2027 — CDS73
   Direction : « Descente ». Un site sombre, comme sous terre, ponctué
   d'intermèdes clairs couleur calcaire. Deux accents aux rôles distincts :
   le rouge Savoie pour agir (s'inscrire), la lueur de frontale pour le temps
   et la lumière (compte à rebours, jauge de profondeur, survols).
