# Creates rn-platform-01 and rn-lab-host-01 from a shared cloud-init template. Sizing comes
# from variables.tf's platform_vm/lab_host_vm objects — baseline defaults, override in
# terraform.tfvars once real load data exists (docs/CAPACITY_PLANNING.md). This module does
# NOT decide the host's final ZFS/storage layout; vm_disk_datastore just names whichever
# Proxmox storage the real disk-inspection checklist points at.
