/* ---------------------------------------------------------
   El Especialista — widget de chat
   Compartido entre vitomartinez.com y 7dias.cl (mismo archivo,
   copiado a los dos sitios). Se apoya en las variables de tema
   que ambos sitios ya definen (--accent, --accent-ink, --text,
   --hair, --muted): hereda el color de marca de cada sitio sin
   configuración aparte. Cero border-radius, sin dependencias
   externas — mismas reglas que el resto del sitio.
