/* pipe.motion · estilo papel
   Paleta: grises de papel + tinta casi negra + un acento amarillo de resaltador.
   El amarillo nunca es color de letra (sobre papel gris no se lee): va como resaltador detrás de la tinta,
   solo en lo que hay que mirar primero: el título, los números y los resultados.
   Nada se mueve salvo el contenido de los videos. */
