/* Khallot — l'en-tête commun à toutes les pages (11 oct. 2026).
   Écrit par deploy/navigation-site.py, chargé sur chaque page, ancien et
   nouveau système. Il porte sa propre classe (kh-entete) pour ne rien
   hériter des anciennes règles de header.site. Le menu du téléphone est un
   <details> : il s'ouvre sans JavaScript ; commun.js le referme proprement.
   Les anciennes pages prennent aussi la police Geist, celle de l'accueil. */
