# Longhorn Helm values — REFERENCE ONLY (not consumed by kustomization.yaml).
#
# The authoritative values are inline in helmrelease.yaml (matching the sibling pattern across
# platform/ — cilium, cert-manager, velero, etc.). This file documents the knobs that matter so a
# reviewer can see intent without reading the HelmRelease. Keep it in sync with helmrelease.yaml.
