/**
 * Widget de chat de TravelBot AI — estilos del front-end (visitantes).
 *
 * Todo el color viene de UNA variable CSS (--travelbot-color), fijada
 * en línea por WidgetRenderer según lo que el administrador eligió en
 * Configuración. El resto de la paleta (grises, fondos) es neutra a
 * propósito: el widget debe verse nativo en cualquier sitio, tema o
 * builder (Elementor/Gutenberg/lo que sea) — no impone una identidad
 * visual propia, se adapta a la del sitio donde vive.
 *
 * Tipografía: se usa el stack de fuentes del sistema del visitante
 * (misma razón: encajar con cualquier sitio) en vez de una fuente
 * propia del plugin.
