variable "domain_suffix" {
  description = "Base domain for this network's libvirt DNS domain (yields \"office1.<domain_suffix>\"). Anchor value per D-106's naming convention; Office1 is a headend, not a per-DC cloud, so it gets one domain, not a per-plane family like modules/dc-planes. NOT re-derived here, pass it in explicitly -- same convention as dc-planes' own domain_suffix input."
