   Un fond quasi-noir, une typographie Geist, des bordures d'un
   blanc très dilué, et un seul accent lavande. Aucune couleur
   saturée : la hiérarchie se fait par l'opacité et l'espacement.

   Tailwind (voir assets/js/theme.js) en sont l'équivalent en
   hex opaques, pour le balisage utilitaire.
