   MOMENT OF TRUTH — CHAT WIDGET
   Estilos del asistente conversacional como overlay flotante.
   El chat en sí mantiene su paleta oscura original (es un "modo"
   distinto al sitio claro — como abrir una consola/terminal premium).

   Estructura:
     #chat-toggle   → botón flotante, esquina inferior derecha
     #chat-overlay  → fondo oscuro + blur sobre el sitio
     #chat-panel    → la ventana del chat en sí (contenido de app.js)
