   Kintsugi — Céline Caisson Suissa
   Charte « Washi, Encre & Or » — proposition n°4

   La palette de l'objet kintsugi lui-même : papier washi, encre sumi,
   et l'or uniquement en couture de réparation. Aucune couleur d'appoint.
   Identité portée par la typographie (Shippori Mincho / Zen Kaku Gothic),
   les coutures d'or irrégulières et les céramiques illustrées au trait.

   Contraste mesuré (WCAG) :
   - encre / papier .................. 15.5:1
   - texte secondaire ................  7.1:1
   - or texte (labels) ...............  7.0:1
   - bouton encre .................... 15.5:1
