# Deploys infra/monitoring/ configs to whichever host needs them. Named monitoring-agent for
# historical reasons in this repo's role list, but it deploys both the "agent" pieces
# (node-exporter/cadvisor/promtail configs, already referenced directly by the platform/
# lab-host compose files) and the central stack's config (Prometheus/Alertmanager/Loki/Grafana
# on rn-platform-01 only).
