boilerplates/traefik/dynamic/ files are rsynced verbatim to lightning-lane,
not rendered through Jinja first. Traefik also processes Go-style
{{ }} templates, so a leftover {{ ansible_managed }} comment line caused
Traefik to reject the entire file with:
ERR /etc/traefik/dynamic/honcho.yml: template: :1: function
"ansible_managed" not defined
Other dynamic configs in this directory deliberately omit the marker;
matching that convention.
