# Met à jour Advanced Custom Fields PRO via Composer (dépôt ACF).
#
# En production, la mise à jour automatique passe par une cron o2switch :
#   scripts/update-acf-pro-server.sh (install : scripts/setup-acf-pro-cron-server.sh)
#
# Prérequis :
#   - Composer installé (https://getcomposer.org/)
#   - .secrets/auth.json (voir .secrets/auth.json.example)
#     Doc : https://www.advancedcustomfields.com/resources/installing-acf-pro-with-composer/
#
# Usage local (depuis la racine du dépôt) :
#   ./scripts/update-acf-pro.sh
#   ./scripts/update-acf-pro.sh --check   # affiche la version sans modifier
#   ./scripts/update-acf-pro.sh --dry-run
