            ADDED BY OVERLAY. The fetched document ships servers[] empty, so paths resolve
            relative to the host it was fetched from. This states that host explicitly so the
            spec is usable standalone.

        This surface returns honest 4xx status codes with a {message,error,statusCode} envelope.
        Its sibling BLM surface at gis.blm.gov does NOT — it returns HTTP 200 with an error
        object in the body. Do not share one error handler across both.
