+# FlowerCore Remote Desktop - Namespace ResourceQuota (GitOps-managed)
+#
+# Codifies the live cap applied on 2026-05-19 after disabling automatic
+# desktop pool prewarm: no more than 15 pods and no more than 8 CPU / 16Gi
+# memory requested across the fc-desktop namespace.
+#
+# ArgoCD adoption note: this manifest uses the same kind/name/namespace as
+# the live ResourceQuota and avoids hook, force, or replace annotations, so
+# automated sync should patch/adopt the existing object in place instead of
+# recreating it.
