       por orden de capas) al mismo azul profundo con el que arranca

       (dashboard/header.html). El enlace activo quedaba con texto y fondo del
       MISMO color: 1.00:1 en tema claro y 1.65:1 en tricorder, medido.
       Estos tokens son locales y su contraste esta medido contra ese fondo; el
       override tricorder del final del fichero los redefine para ese tema.
