   PACIFIC HOTEL BROKER — HOME.CSS
   Refonte 2026. Source de vérité du style de la home.
   Ne charge QUE sur la page d'accueil (enqueue conditionné à is_front_page()).
   Tous les sélecteurs sont scopés à body.phb-home pour ne PAS affecter le reste
   du site (cf. CLAUDE.md, périmètre strict).

   Sommaire :
       1.  Design tokens
       2.  Smooth scroll (scope home)
       3.  Reset minimal (:where pour spécificité 0)
       4.  Masquage des éléments du thème parent (sur la home uniquement)
       5.  Utilities : container, eyebrow, skip-link, buttons, link-arrow
       6.  Navigation (incl. logo)
       7.  Sélecteur FR · EN
       8.  Burger mobile
       9.  Section Hero
       10. Footer custom (phb-footer)
       11. Responsive
       12. Accessibilité (prefers-reduced-motion, focus visible)
