/* Les boutons/toggles ne doivent pas se comprimer les uns les autres : DSFR calcule la
   largeur du libellé d'un fr-toggle en fonction de la largeur de son conteneur
   (calc(100% - 2rem)), donc un conteneur trop comprimé fait retomber le texte
   caractère par caractère. On fige une largeur confortable et on laisse la barre
   passer à la ligne (flex-wrap) plutôt que d'écraser chaque contrôle. */
