/* Deux tentatives précédentes (override par classe, puis sélecteur à 2 classes)

   classes partagées plutôt qu'un simple oubli de couleur. Le bouton n'utilise
   plus .sf-btn-create/.sf-demo-locked-cta du tout (cf. HomePage.razor) : la couleur
   et le fond de base sont en style inline (spécificité maximale, gagne face à
