/* ==========================================================================
   Petit agent Walexia (assets/js/agent.js, includes/agent.php) — charte Walexia claire (29/10/2026, retour de
   l'utilisateur : « trop sombre », logo Walexia, police plus moderne, moins de texte).
   Feuille autonome : ne dépend ni de walexia.css ni de walexia-da2.css, et résiste aux styles du thème
   (sélecteurs préfixés par .wxa).
   - Blanc et vert Walexia : bouton d'ouverture et bouton principal en dégradé sur #34D36B, texte encre (8,6:1),
     jamais de vert foncé en fond ; messages du visiteur en bulle verte claire, comme sur WhatsApp.
   - Logo Walexia dans l'en-tête, pictogramme sur le bouton et à côté des réponses.
   - Plus Jakarta Sans (assets/fonts/), Arimo à défaut.
   - Bouton en bas à droite, panneau ancré au même endroit (400 px), plein écran sous 640 px.
