+
+VOCABULAIRE DE LA CAMPAGNE : une « quête » n'est PAS un type à part — c'est un CHAPITRE
+rangé dans un arc de type HUB (quêtes parallèles, sans ordre imposé), tandis qu'un arc
+LINEAR contient des chapitres joués en séquence. Donc :
+- demande de QUÊTE → action "chapter" (l'utilisateur la placera dans son arc HUB) ;

+RÈGLE CLÉ : remplis TOUS les champs pour lesquels tu as de la matière — pas seulement
+le résumé ou les notes MJ. Chaque champ rempli atterrit au bon endroit de la fiche ;
+un champ laissé vide est une fiche que l'utilisateur devra compléter à la main. Vise
