usage() {
  cat <<'USAGE'
Usage:
  scripts/cluster_power_console.sh [--repo-dir <path>] [--delegate-host <host>] <shutdown|startup> [recovery-script-options...]

Purpose:
  Friendly manual entrypoint for running cluster power recovery from a remote console.
  Prefer a sibling cluster_power_recovery.sh when installed as a standalone helper.
  Otherwise use a repo checkout if available, or delegate to another host.

Defaults:
  --repo-dir       $HOME/Development/titan-iac
  --delegate-host  titan-24

Examples:
  scripts/cluster_power_console.sh shutdown --execute
  scripts/cluster_power_console.sh startup --execute --force-flux-branch main
  scripts/cluster_power_console.sh --delegate-host titan-24 shutdown --execute
