/* Page publique de démonstration du tableau de bord.
   ------------------------------------------------------------------
   Cette page mélange deux mondes : le chrome marketing du site (bandes
   d'explication, appel à l'action) et le rendu réel de l'espace client,
   qui vient de app.css. On ne réutilise pas style.css : ses règles
   entreraient en conflit avec celles de app.css sur .logo, .btn, body…
   Tout ce qui appartient à cette page est donc préfixé .demo-. */
