+En mode `PRONOTE_AUTH_MODE=qr_token`, `PRONOTE_QR_PIN` déchiffre le QR code
+exporté depuis le site web Pronote. Si le compte exige un second facteur,
+configurez aussi `PRONOTE_ACCOUNT_PIN` avec le PIN du compte. Ce PIN est
+transmis uniquement à `pronotepy` lors de l'enrôlement QR et des connexions par
+token ; il n'est jamais écrit dans `.pronote_auth_state.json` ni dans les logs.
