   Charte « moderne » : bordeaux du logo Morale de l'Histoire,
   Young Serif pour les titres, Inter pour le texte.
   Young Serif n'existe qu'en romain (pas d'italique ni de gras) :
   les textes « en italique » sont donc composés en romain ou en Inter.

   Organisation :
     1. Variables (couleurs, polices, dimensions)
     2. Base commune
     3. Composants communs (surtitre, pastille, bouton, barre du haut,
        couverture 3D, pieds de page)
     4. Page d'accueil       → body.page-home
     5. Mentions légales     → body.page-legal
     6. Page de confirmation → body.page-merci
