/* ==========================================================================
   FinaPilot — design system « Éclat »

   Parti pris : la lumière. Un papier clair et chaud, de l'encre profonde,
   et la couleur tenue pour ce qui compte — la marque, la donnée, l'action.
   Les surfaces flottent sur des ombres en couches plutôt que sur des traits ;
   les rayons sont généreux ; la typographie respire.

   Le thème sombre n'a pas disparu : il est passé en option, sous
   `[data-theme="dark"]`. Toutes les couleurs sont des variables, donc une
   seule bascule suffit à retourner le site.
