# Run ONCE, on the manager node only (vps2 — the box with headroom for prod's
# and beta's Swarm stacks and their local volumes). Initializes the Swarm
# advertising the WireGuard address, so cluster traffic never touches the
# public interface. Run setup-wireguard.sh on all THREE nodes first (vps2,
# vps1, and the desktop — see
# docs/runbooks/implementation-handoff.md Track B steps 2-3).
