/* =========================================================================
   Système visuel Kuaba — page d'accueil.

   Grammaire reprise de la référence : héros pleine largeur, barre de recherche
   en chevauchement, sections rythmées par un intertitre centré (surtitre + titre
   + chapô), grilles de cartes, un panneau sombre qui marque la bascule voyageur
   -> hôte, bandeau d'inscription pour finir.

   Les couleurs passent par les variables du gabarit (--base, --base-two) : un
   changement de couleur de marque en administration suit automatiquement.
