Every environment value is a ${VAR} for the caller to substitute: hostname,
images, storage, ingress class, TLS issuer, Vault server and path, timezone,
retention. Nothing in k8s/ names a host, a realm, an agent or an estate.
Removed: the Flux plumbing under dev/, which described one deployment, and the
ExternalSecret pulling a specific agent's Keycloak client secret. Both belong to
whoever deploys this. The lab CA ConfigMap goes with them — the mount stays,
parameterised and marked optional, because 'trust a private CA' is a property of
an environment and not of n8n.
The README is now the template's: how to consume it, what every variable means,
and the three things it deliberately does not do.

# A StatefulSet rather than a Deployment: one identity, one volume, and no

# window where two pods hold the same data directory. The volumeClaimTemplate

# also means the claim is not deleted with the workload — losing the workflows
|
|
# to a `kubectl delete deploy` would be an avoidable way to lose them.
