+# self-hosted runner pods (e.g. FlowerCore.Print.Web `help-screenshots`)
+# can reach the grid. Without this allow, the session POST to
+# `selenium-hub.selenium.svc.cluster.local:4444` was DNAT'd to the hub
+# pod IP and then dropped at the Calico ingress hook — Selenium UI showed
+# 0/4 sessions while the .NET HTTP client timed out at 60s. Same family
+# as `feedback_netpol_dnat_backend_port`, wrong-source-namespace flavor.
