/* Codename (Toy Story style) - bandera de Santa Cruz: franjas horizontales
   verde-blanco-verde. El degradado usa background-size en "em" para adaptarse
   al tamano de la fuente (independiente de la longitud del texto, responsive
   y zoom). La bandera de Santa Cruz tiene las franjas HORIZONTALES: el
   degradado debe ir de arriba hacia abajo (to bottom).

   Las franjas no son 0/33.3/66.7 porque el area visible de los glifos no
   ocupa todo el em (queda espacio debajo de la linea base): con esa division
   la franja verde inferior quedaba casi fuera del texto y se veia solo
   verde-blanco. Con cortes en 25% y 47.5% (verificado en Chrome a varios
   tamanos de fuente y line-height) las tres franjas caen dentro del area
   visible del texto y quedan visualmente equilibradas. */
