   JustYourNote — identité visuelle "carnet de notes gamifié"
   Signature : les notes se lisent sur une règle graduée (0→20), les badges
   sont des tampons de correcteur (cachets circulaires, légèrement inclinés).
   Police manuscrite en accent (annotations, badges, citations), grotesque
   propre pour l'interface, mono pour les codes/chiffres.
