   esquina superior derecha de cada sección — el gesto del nombre
   Empleabilidad 360° — más una trama de puntos discreta en la esquina
   inferior izquierda.

   POR QUÉ NO PUEDE DESFASARSE: a diferencia de una cinta que cruza
   secciones, estos ornamentos son AUTOCONTENIDOS. Tienen tamaño fijo (rem),
   idéntico en todas las secciones, anclados a la esquina: nunca se estiran
   con la altura de la sección ni tocan la costura con la siguiente, así que
   no existe empalme que pueda quedar cortado o corrido. Los anillos se
