   Lo nuevo: el ocre no pinta secciones enteras, arma BLOQUES.
     · los rótulos numerados pasan a chip ocre
     · las fichas de servicio se leen como un muro: dintel ocre,
       módulo 2x2 del manual y bloque ocre de cierre
     · los pictogramas de sistema (cuadrado, contorno, círculo,
       rombo) marcan las listas
