- Page SaisirCodeUnique connectée au backend avec overlay Félicitation
- Page Perdu pour les codes invalides/déjà utilisés
- MesGains redesigné en timeline avec appel API et bouton saisir nouveau code
- Profile redesigné avec onglets et données depuis localStorage
- Service game.js ajouté (participateApi, myGainsApi)
- Ajout des designs de référence dans frontend/Design/
