/* Cette regle forcait le texte en blanc sur les boutons pleins. Elle etait portee par

   s'appliquait donc qu'apres un aller-retour par le theme sombre, et dormait le reste
   du temps. La retirer avec le theme aurait ete plus juste que de la generaliser :
   .btn-primary et .nav-cta declarent deja « color: white », et le !important ecrasait
   les boutons ajoures des cartes de tarifs — texte blanc sur fond blanc. */
