/* ============================================================
   Polices autohébergées (RGPD : plus d'appel à Google Fonts)
   ------------------------------------------------------------
   1. Récupère les fichiers .woff2 avec le CSS déjà prêt sur
      https://gwfh.mranftl.com/fonts pour chacune de ces polices
      (coche exactement ces graisses) :
        - Spectral        : 400, 500, 600, 700, + 500 italique
        - Lato            : 300, 400, 700
        - Source Code Pro : 400, 500, 600
        - Space Grotesk   : 500, 600, 700
   2. Dépose les fichiers .woff2 dans un dossier /fonts/ à la
      racine du site.
   3. Remplace tout le bloc ci-dessous par celui que l'outil
      génère pour toi (il te donne un @font-face distinct par
      graisse, avec les noms de fichiers exacts) — ce qui suit
      n'est qu'un squelette à adapter, pas des fichiers réels.
      Une police statique ne peut PAS utiliser une plage de
      graisses (ex. "400 700") sur un seul fichier : il faut un
      bloc par graisse, chacun avec sa valeur exacte.
