-# Authentik OIDC backend
-# ArgoCD-managed. BlueJay Lab.
-#
-# Stack:
-#   - PostgreSQL 16 StatefulSet (single replica, Longhorn RWO 5Gi)
-#   - Redis 7 Deployment (no persistence — session/cache only)
-#   - Authentik server + worker Deployments (image ghcr.io/goauthentik/server:2024.12.3)
-#   - Media PVC shared between server + worker (Longhorn RWO 2Gi)
-#   - Certificate via step-ca-acme ClusterIssuer
-#   - Traefik IngressRoute at id.iamworkin.lan
-#
-# Secrets come from 1Password item "authentik-credentials" (IAmWorkin vault, id y6i74ch22q5wvm7znquq4nhhcu)
-# via the OnePasswordItem CRD, materialized into k8s Secret authentik/authentik-credentials.
-#
-# Why the discovery URL is /application/o/pimanager/ : Authentik issues per-application OIDC providers.
-# The pimanager OIDC application/provider is created after the cluster pods are healthy (manual or
-# via API once the bootstrap token is available — see Notes substrate).
