   Signatura visual: la "cruz de registro" (registration mark) que se usa en
   preimpresión offset para alinear las planchas de color CMYK. Aparece como
   animación de entrada del titular, como viñeta de sección y como marcador
   de los pasos del proceso de trabajo — un guiño real al oficio, no un
