/* ==========================================================================
   Demande de mandat administratif : feuille commune aux trois pages
   /public/mandat-administratif, /en/public/…, /es/public/…
   --------------------------------------------------------------------------
   Chaque page avait sa copie inline, et les copies avaient dérivé (sélecteur
   de durée à cinq colonnes sur les miroirs, pas de code promo). Le style vit
   désormais ici, une seule fois, comme /public/join/join-guide.css.

   Le footer n'est pas stylé ici : il a sa propre feuille
   (/public/site-footer.css), qui interdit d'en remettre dans une page.
