   Trazo — hoja de estilos
   Dirección: hoja topográfica. Papel gris verdoso de mapa suizo,
   tinta pizarra y un único color de sobreimpresión (magenta de
   imprenta) reservado para tu trazo. Las cifras usan Archivo
   expandida, como un cuentakilómetros; las etiquetas, Archivo
   estrecha. Una sola familia, el eje de anchura hace el trabajo.
