   Sistema visual heredado del prototipo, ya validado con el negocio.

   Dirección: instrumento de taller, no página web. La pantalla que más se
   usa es el pesaje, de pie frente a la gramera, con las manos ocupadas y
   luz variable. De ahí salen las decisiones: alto contraste, números
   grandes en mono tabular, ámbar de señalética industrial para el paso
   activo, y el color de los propios tintes como único acento cromático.

   IBM Plex nació para documentación técnica y máquinas. La versión mono
   se usa para todo número que el colorista deba leer o comparar: sus
   dígitos tienen el mismo ancho, así las cifras se alinean en columna y
   el ojo no se pierde entre 391.75 y 254.96.
