/*
THESIS: La matrice calculée apparaît sous la date et précède un voyage vertical sobre dans ses dix zones.
OWN-WORLD: Graphite profond, argent HEYOKA, Zodiak et Sofia Sans; aucune plage blanche ni effet ajouté aux lettres.
STORY: Saisir une date, voir la vraie matrice, parcourir ses zones, puis ouvrir l’atelier seulement si nécessaire.
FIRST VIEWPORT: Le calculateur reste immédiat; le résultat s’insère dessous et repousse naturellement le récit.
FORM: Scrollytelling sombre avec vignette fidèle issue du calcul, sans escalier, sans typographie truquée et sans outils visibles par défaut.
