+# ArgoCD Install — v3.4.2
+#
+# This is NOT applied by ArgoCD itself (chicken-and-egg).
+# It is the ONE manual bootstrap step:
+#
+#   kubectl create namespace argocd
+#   kubectl apply -n argocd --server-side --force-conflicts -f install.yaml
+#
+# After this, everything else is driven by apps-of-apps.yaml.
+#
+# To upgrade ArgoCD: update the version below and re-apply.
+# --server-side --force-conflicts is required due to CRD size limits.

+# We reference the upstream manifest directly rather than vendoring it.
+# Pin upgrades by changing the version tag above and re-running the command.
