## Carte des missions du niveau scolaire du profil. Le prototype initial
## (cahier des charges §15) se limitait a trois lieux ; le perimetre a ete
## etendu (docs/specs/decisions.md, points 25 et 27). La position de chaque
## mission vient de data/missions/*.json (fractions 0..1 de la zone de
## carte), jamais d'une position fixe en dur dans le script. Un profil CE2
## peut basculer sur la carte CE1 pour revoir les notions precedentes.
