The first deploy of the grafana unit failed: 'stat /root/.config: permission
denied', exit 1, restart loop. Cause — the repo-root .env that the compose
service used to pick up is a gluetun env file, and it carries HOME=/root (and
the WireGuard keys). Pointing the unit's [Service] EnvironmentFile at it sets
HOME for the service, so podman looks for its configuration under /root.
grafana now reads /home/dank/Containers/grafana/env, the per-service file the
deployer seeds from dankclaw/.env with a single-variable filter — the same
shape caddy, pihole, copyparty, romm and seerr use. The seed is validated, so
a missing secret fails the deploy loudly instead of starting a container whose
OAuth login cannot complete. The value was copied to dankclaw/.env, which is
where dankclaw/.env.example already documented it.
