+# GX10 Piper TTS — telephony /tts endpoint on the GX10 RKE2 cluster.
+# Applied DIRECTLY via the GX10's own kubectl (KUBECONFIG=/etc/rancher/rke2/rke2.yaml);
+# the GX10 cluster is NOT yet under the old-cluster ArgoCD. CPU-only (no GPU request)
+# so it co-resides with the GPU-holding Ollama pod without contending for the GB10.
+# Image is imported into RKE2 containerd (imagePullPolicy: Never).
+# Telephony reaches it at http://10.0.56.14:30850 (NodePort, MGMT VLAN 56).
