/* ka-a.js v2 — analytics first-party Groupe KA (administration-ka.com)
 * Léger, asynchrone, sans cookie tiers, sans fingerprinting, sans contenu saisi.
 * - visitor_id (KA_VID, localStorage) : anonyme, persistant, dédup refresh
 * - session_id (KA_SID) : nouvelle session après 30 min d'inactivité
 * - page view : chargement + navigations SPA (pushState/replaceState/popstate)
 * - heartbeat 25 s : SEULEMENT si l'onglet est visible ET activité < 60 s
 *   (scroll/pointeur/clavier/touch — on note QU'une interaction a eu lieu, jamais son contenu)
 * → un onglet fermé ou inactif disparaît du compteur « en ligne » en ~2 min. */
