   Demo del chatbot de WhatsApp — /servicios/software

   Simula la interfaz de WhatsApp en modo oscuro. NO usa la marca ni el logo
   de WhatsApp: solo el lenguaje visual, y el demo va rotulado como
   simulación para que nadie lo confunda con la app real.

   Solo se carga en la página del demo, no en todo el sitio.
