# Healthcheck - проверка доступности сервера
# Increased start-period to 45s to allow server initialization (Isar DB, cron jobs, etc.)
# Isar может долго инициализироваться при первом запуске или при большом объеме данных
# Используем 127.0.0.1 для healthcheck (внутри контейнера работает даже если сервер слушает на 0.0.0.0)
# Сервер работает только по HTTP (HTTPS обрабатывается на уровне reverse proxy в Coolify)
# Пробуем curl, если не работает - используем wget как fallback
