  # HEALTH INDICATORS — TWO SETTINGS THE CHART FIXES IN THE TEMPLATE
  #
  # The chart sets these two as plain environment variables, not as values,
  # because urlaubsverwaltung.env below already overrides anything:
  #
  #   MANAGEMENT_ENDPOINT_HEALTH_GROUP_READINESS_INCLUDE=readinessState,db
  #     puts the datasource into the readiness group, so a database outage
  #     takes the pod out of Ready instead of leaving it serving errors (#218).
  #     The liveness group stays untouched on purpose — an outage must keep
  #     traffic away, not restart the pod in a loop.
  #   MANAGEMENT_HEALTH_MAIL_ENABLED=false
  #     removes the mail indicator, which otherwise pins the aggregate
  #     /actuator/health at 503 DOWN forever, because the chart's mail wiring
  #     points at localhost:1025 where nothing listens (#217).
  #
  # THE CONSEQUENCE TO KNOW BEFORE IT BITES: whoever later configures real mail
  # delivery (SPRING_MAIL_HOST/SPRING_MAIL_PORT via urlaubsverwaltung.env) MUST
  # switch the indicator back on in the same change:
  #
  #   env:
  #     - name: MANAGEMENT_HEALTH_MAIL_ENABLED
  #       value: "true"
  #
  # Left at false, /actuator/health keeps answering 200 while the configured
  # mail server is unreachable and no notification mail is delivered. The
  # setting trades a permanently false alarm for silence, and silence is only
  # correct as long as there is nothing to report about.
  #
  # That override repeats a name the chart already sets, and env is additive, so
  # it renders the variable twice. At INSTALL time both entries reach the pod and
  # the later one — yours — wins in the container. Added to an ALREADY INSTALLED
  # release it is lost instead: Kubernetes merges env by name, the pair collapses
  # to the chart's own entry, and helm still reports a successful upgrade. The
  # override does not fail loudly, it fails silently. See the "env IS ADDITIVE
  # ONLY" section of NOTES.txt — the switch has to go in at install time, and
  # after any such change the result belongs verified on the live Deployment.
