// The legacy admin and gallery pages show a server refusal's reason (#220, PR #289 review I1 and M8): a job that
// runs in the workspace refuses their record-changing requests, and a corrupt config.json refuses a settings save.
// Each page must name the reason, not report a lost connection, a bare HTTP status or a success.
