  Palette anthracite chaude : sombre par défaut, jamais froide.
  Fraunces (serif douce, optical sizing) pour les titres, en italique fine.
  Nunito Sans porte le texte courant avec des formes rondes et lisibles.
  DM Mono signe les petits détails (nav, labels, dates) pour un contraste net.
  Cartes aux coins arrondis, ombres douces plutôt que bordures dures.
