   fonts.css - polices auto-hebergees (woff2, subset latin + latin-ext)

   CSP du site a deja "font-src 'self'" : rien a changer cote CSP.

   Montserrat 700/800/900 et DM Sans 300/400/500 sont servies par un seul
   fichier variable par sous-ensemble (Google renvoie le meme fichier pour
   ces 3 poids quand ils sont demandes ensemble : verifie par hash md5,
   fichiers identiques). Poppins 700/800 sont deux fichiers statiques
   distincts (pas de variable ici), gardes separes.

   Polices de repli a metriques ajustees (Arial) calculees avec fontTools
   (xAvgCharWidth / ascent / descent, formule size-adjust usuelle des outils
   de generation de police de repli) :
   corrige le CLS de 0,366 mesure sur les pages page-backlinks.php (constat
   n°3 de AUDIT-PERF-2026-09-30.md), le texte de repli occupe deja la place
   du texte final avant meme que Montserrat/DM Sans soient charges.
