/* /api — portada: el catálogo de una editorial ficticia («Editorial LEO») con la integración de Nubo.
   Se abre un material, aparece «Adaptar con Nubo» y se ve el antes frente al adaptado.
   Se apoya en centro.css (.cx-lienzo, .cx-app, .cx-pill) y en api-demo.js. Prefijo api-.
   Estado por defecto (sin JS, con «reducir movimiento» o dentro del editor) = el final: antes y después. */
