# Wave 7 — Kong, the cluster's internal API gateway (namespace `api`).
#
# Sits between nginx and the backend services: nginx owns the edge and TLS,
# Kong owns routing policy, auth and rate limiting. Wave 7 puts it after the
# data/messaging tiers it fronts and before the wave-8 applications that
# publish routes into it.
#
# DB-less: routing config comes from Kubernetes objects (Ingress with
# `ingressClassName: kong`, plus KongPlugin/KongConsumer CRDs), so git remains
# the source of truth and there are no migration Jobs on upgrade.
#
# CRDs ship in the chart's crds/ directory; ArgoCD applies those by default
# (helm.skipCrds is left false).
