The first real deploy left the site on 502 and this is why. podman builds an OCI image by default and drops the Docker HEALTHCHECK instruction, so the app container has no State.Health at all; the role waited on that field, exhausted its retries and failed the play, so the caddy role never ran and Caddy kept proxying menu.hopsngrains.com to the old nginx container that is now gone. The wait now asks the app itself: docker exec node -e fetch /healthz, which needs no healthcheck and no DNS. And because the address may still be claimed by the snippet the retired nginx-menu playbook wrote, the caddy role drops that marker before writing its own - two blocks for one address make Caddy refuse the config, and a refused reload quietly leaves the old proxy in place. check-site also asked for the font the old design used, so it would have failed a healthy site; it checks one we ship.
