published port as `192.168.1.130`, and Caddy rightly strips their `Cf-Access-*`. Send them from a
container on another network, as cloudflared's are (#209).
The three containers resolve names through Cloudflare (`dns: [1.1.1.1, 1.0.0.1]` in the compose
file), not the router: the LAN's DNS is NextDNS, which answers for a domain it filters with its own
block page, and ipx then logged a feed as failing with `invalid peer certificate: UnknownIssuer`
(tomrenner.com, 2026-10-17). Docker's own DNS still answers for the services' names first.
**Name the service.** A bare `up -d` recreates every container in the project, which once the
split lands means the frontend and directory too. Run `pull` before `up`, because `up` reuses whatever `latest` the host already has.
