    Dark, and committed to it: the identity is built on the gem glowing against a near-black
    ground, and a light variant would be a different design rather than a tint. Every colour is
    painted explicitly so nothing borrows a value from the visitor's browser.

    decoración y no como el menú.

    Sube a 15.5px, peso 500 y un gris bastante más claro. El subrayado al pasar por encima está
    para lo otro que faltaba: que se note que son enlaces antes de hacer clic.
