   BOTONES INTERACTIVOS
   Port del componente <InteractiveHoverButton>: al pasar el cursor, la cara
   base se desliza y se va, entra la segunda cara con la flecha, y el punto
   crece hasta llenar el botón.

   Dos diferencias deliberadas con el original: se conserva el radio afilado
   del sitio (no la píldora) y cada botón mantiene su ícono propio en la cara
   base — la flecha diagonal significa "abre en otra pestaña" y esa señal no
   se regala.
