/* Ugokami — « papier qui bouge » (動く紙).
   Aplats, ombres dures en feuilles décalées, aucun dégradé, aucun flou (sauf
   le menu mobile flottant), aucun backdrop-filter. Polices système seulement.
   Sombre par défaut ; clair quand le système le demande.
   Montrer plutôt que dire : peu de mots, en gros ; de grands visuels. */
