   Cockpit — assistant.css

   valeurs de repli) : clair / sombre suivent la page hôte. Préfixe .cka-.
   Dans l'application, le bouton se range AU-DESSUS du bouton de messagerie
   (.msg-fab, 56 px puis 48 px sous 560 px) ; sur la vitrine mobile, au-dessus de
   la barre « Offre Pionnier » quand elle est visible.
