# Two code paths:
#   1. Fresh run (system_cfg undefined): normalize from raw `system` input.
#   2. Pre-computed (system_cfg already set, e.g. from main project's deploy_iac):
#      merge with bootstrap system_defaults to fill missing fields (luks, features,
#      etc.) that bootstrap expects but the main project doesn't set, then derive
#      convenience facts (hostname, os, os_version).
