## Description

cairn is the page you hand to the people you host services for: family, a club, whoever ends up using your server. One YAML file in, a static multilingual directory out, with no account to create, no database and no outbound requests. It shows your services and nothing else: no widgets, no Docker socket, no metrics. Each service can show a live status pill pulled from Gatus or Uptime Kuma, so visitors see what is up before they click, and cairn serves its own legal and privacy pages. It ships as a single static Go binary in a FROM scratch image, around 4 MB to pull, and it writes nothing at runtime, so it runs read-only with every Linux capability dropped.
