/*
  Kantara Operations — feuille de style unique du site.
  Choix techniques :
  - Propriétés logiques CSS (margin-inline, text-align: start/end, etc.) partout où c'est possible,
    pour que la mise en page se retourne automatiquement en arabe (dir="rtl") sans feuille séparée.
  - Police système empilée (pas de Google Fonts) : meilleure performance et meilleur rendu de
    l'arabe que la plupart des polices web importées ; html[lang="ar"] utilise une pile dédiée.
  - Couleurs en custom properties pour ajuster la palette facilement plus tard.
  - Contrastes vérifiés WCAG AA : #6050DC et #2E6F5E sur blanc >= 4.5:1.
