3 voting etcd members peering on the LAN. All 3 nodes run Longhorn with 3-replica
HA storage (verified: all 17 PVCs have replicas across all nodes). All 3 nodes are
schedulable for workloads (no `NoSchedule` taints) for better resource utilization.

🔴 **Control-plane scheduling controlled via Terraform.** To enable/disable workload
scheduling on a control-plane node, edit `terraform/terraform.tfvars` →
`controlplane_configs.<node>.allow_scheduling` (true/false), then:
```bash
cd terraform
terraform fmt && terraform apply
talosctl apply-config --nodes <node-ip> --file ../cluster-config/<node>.yaml --mode no-reboot
```
Do NOT manually `kubectl taint` — Talos will revert on next reconcile. All changes
must flow through Terraform to persist across reboots.
🔴 **ALWAYS run `terraform fmt` after any terraform code changes.** Before commit:
```bash
terraform fmt -recursive terraform/
