/* ------------------------------------------------------------
   1. POLICES
   ------------------------------------------------------------
   Muro (logo) est installé dans /fonts et activé ci-dessous.
   Deux styles disponibles :
     - 'Muro'       → Muro.otf       (droit — utilisé pour le logo)
     - 'Muro Slant' → Muroslant.otf  (penché — variante)
   Pour passer le logo en penché : dans --font-logo (plus bas),
   remplace 'Muro' par 'Muro Slant'.

   La police de texte Neue Haas Grotesk Display Pro est installée
   dans /fonts (3 graisses : 400 / 500 / 700) et activée plus bas.
