   26. ROBOT VIAJERO
   El robot acompaña al scroll desde el hero hasta la sección
   siguiente. El desplazamiento vertical lo hace `position:sticky`
   (sin JavaScript); el corrimiento horizontal lo interpola el módulo 3D
   según el avance dentro de .escena, igual que el acercamiento a la cara.

   La caja pegajosa mide lo mismo que el robot y el hero se sube con un
   margen negativo. Así el robot se despega justo al terminar .escena y
   se va con ella; con altura cero se quedaba flotando sobre la sección
   siguiente y tapaba su contenido.
