   Polices — auto-hébergées dans fonts/ (licence SIL Open Font License).
   Aucun appel à Google Fonts : le site reste sans dépendance externe, et
   aucune requête vers un tiers n'est faite depuis le navigateur du visiteur.

   Sous-ensemble « latin » uniquement : il couvre l'intégralité du français,
   y compris œ (U+0153), les guillemets « », le tiret cadratin et l'euro.
   Le caractère → des listes et des liens est hors de ce sous-ensemble ; il
   est rendu par la police système, comme avant.

   Inter est une police VARIABLE : un seul fichier couvre 400 à 700, d'où la
   plage déclarée en font-weight. Poppins reste statique, une graisse par
   fichier (600 pour les en-têtes de tableau, 700 pour les titres).
