/* Les couleurs qui portent du texte atteignent 4,5:1 contre leur fond, les
   éléments non textuels 3:1. Le ratio noté en regard de chacune est mesuré
   contre --paper-off (#f7f9fc), le fond du body, et non contre du blanc pur :
   c'est le pire cas, les cartes étant plus claires que la page.
   --am31-blue reste la couleur de marque pour tout ce qui ne porte pas de
   texte (barre de progression, puces, bordures, point du logo) : à 3,01:1
   il ne convient pas à du texte, d'où --am31-blue-dark.

   Thème : chaque token s'écrit light-dark(clair, sombre) et le choix vient de
   color-scheme, posé plus bas. Une seule palette à maintenir au lieu de deux
   blocs à garder synchronisés. En sombre, les teintes de texte s'éclaircissent
   au lieu de s'assombrir ; les ratios sont mesurés par axe-core sur les deux.
   Le sombre est un noir pur (#000, écran OLED) : les cartes se distinguent par un contour,
   pas par une ombre ni par un gris plus clair. */
