/* ==========================================================================
   Grotte del Faedo-Casaron — TOTEM museale, schermo touch fisso 16:9
   Direzione estetica: "rilievo speleologico" (stessa di prima: calcare in
   ombra, bagliore ciano di lampada frontale, accento ambra da caschetto).
   Qui pero' cambia la meccanica: schermo a rapporto fisso, mai scroll,
   navigazione a schermate con grandi bersagli touch.
