/* ============================================================
   POLICE DU NOM/PRÉNOM — Section à personnaliser
   ============================================================
   Le nom de l'artiste utilise la variable --serif définie dans :root.
   Pour changer la police, deux options :

   OPTION A — Google Fonts (en ligne, gratuit) :
   Exemples disponibles :
     'Cormorant Garamond' → élégant, calligraphique
     'IM Fell English'    → ancien, littéraire
     'Libre Baskerville'  → classique, lisible
     'Josefin Sans'       → moderne, géométrique
     'Great Vibes'        → cursive, manuscrite
     'Cinzel'             → inspiré de l'antique romain
   Procédure :
     1. Aller sur fonts.google.com, choisir la police
     2. Copier le lien <link> dans includes/header.php (remplacer Playfair Display)
     3. Modifier --serif ci-dessous : --serif: 'Nom Police', serif;

   OPTION B — Police personnelle installée sur votre PC (web locale) :
   Procédure :
     1. Copier le fichier .ttf ou .otf dans public/assets/fonts/
     2. Ajouter une déclaration @font-face (voir exemple ci-dessous)
     3. Modifier --serif avec le nom choisi

   Exemple @font-face pour police locale :
   @font-face {
     font-family: 'MaPolice';
     src: url('../assets/fonts/mapolice.ttf') format('truetype');
     font-weight: normal;
     font-style: normal;
   }
   Puis dans :root : --serif: 'MaPolice', Georgia, serif;

   POUR CHANGER UNIQUEMENT le nom/prénom (logo header + hero h1) :
   .logo-name { font-family: 'MaPolice', serif; }
   .hero h1   { font-family: 'MaPolice', serif; }
