/*
 | mailbox_ai — WIDGET CHATBOT GLOBAL (bouton flottant sur toute page admin)
 | -------------------------------------------------------------------------
 | ⚠️ ZERO REGRESSION : ce fichier est charge sur TOUTES les pages admin du CRM.
 | Regles STRICTES :
 |   - TOUTES les classes sont prefixees .mbxw-  (aucun selecteur generique :
 |     pas de *, body, a, p, ul... -> impossible de "deborder" sur Perfex).
 |   - toutes les proprietes sont scopees sous #mbxw-root / .mbxw-*.
 |   - box-sizing remis a border-box UNIQUEMENT sous #mbxw-root (jamais global).
 |   - z-index eleve mais SOUS les modales Bootstrap de Perfex (backdrop 1040 /
 |     modal 1050) -> une modale critique passe toujours DEVANT le widget.
 |   - le widget est INERTE tant qu'il n'est pas ouvert (seul le bouton s'affiche ;
 |     le panneau est display:none -> n'intercepte aucun clic de la page).
