  # ============================================================================
  # SINGLE-NODE / ALL-IN-ONE INSTALL IMAGE
  # ============================================================================
  # This netboot image is the bare-metal companion to the QEMU-first
  # `single-node-quickstart` profile. It keeps only the minimum VM stack in the
  # image by default and leaves DNS, load-balancing, storage, API, metrics, and
  # Kubernetes layers as explicit add-ons in the final installed system.
  #
  # Included by default:
  # - Chainfire: local coordination and placement metadata
  # - FlareDB: metadata/event storage
  # - IAM: local identity plane for the dev profile
  # - PrismNET: VM networking control plane
  # - PlasmaVMC: VM control plane
  #
  # Intentionally not included by default:
  # - Deployer / Nix Agent: rollout and install authority
  # - Fleet Scheduler / Node Agent: native host-service placement
  # - K8sHost: tenant pod and service control plane
  #
  # Optional after install:
  # - LightningStor, CoronaFS
  # - FlashDNS, FiberLB
  # - API Gateway, Nightlight, CreditService
  # - K8sHost
  # ============================================================================
