            Stable machine-readable error code — branch on this rather than

            matching the human `error`/`message` strings. Domain codes include

            `insufficient_neo_credits`; otherwise it mirrors the error kind

            (e.g. `forbidden`, `invalid_request`, `not_exists`,
            `already_exists`).
