services/caddy_playbook.yml was the one play still targeting a location
group (vps) rather than a role group. The two coincide today — vps is
exactly vipy, watchtower and spacey, the three hosts with
/etc/caddy/sites-enabled — but adding a fourth VPS that does not run
Caddy would have silently pulled it into the play.
[caddy:children] is edge + monitoring + vpn_control. Verified the play
selects the same three machines before and after.
