/* ═══════════════════════════════════════════════════════════════════
   Demo en vivo del software (plataforma.html): una ventana de Qubiko
   que se «usa» sola con un ejemplo real. El alumno escribe su idea, la
   IA contesta y el proyecto se abre pestaña por pestaña. Las imágenes
   son capturas reales del proyecto «Rover explorador».
   La animación la mueve js/demo-software.js; sin JavaScript o con
   «reducir movimiento» se ve el resultado final, quieto.
