The version moves from the header to a "Powered by Jarl" footer. A build of a release tag (HEAD tagged v<VERSION>, no tracked changes; the release workflow sets RELEASE_TAG) shows and links the release; any other build shows and links its commit, marked -modified with uncommitted changes. jarld version, jarl --version, /status and /auth/whoami report the same.
