        Error identifier. For domain rejections and transport errors
        (`401`/`404`/`429`/`500`) this is a stable, machine-readable snake_case
        identifier that is part of the API contract and safe to branch on, e.g.
        `insufficient_margin`, `insufficient_balance`, `order_not_found`,
        `reduce_only_invalid`, `unauthorized`, `not_found`. For `400` it is a
        human-readable validation detail whose wording may change. See the Error
        handling guide for the domain identifiers. (Post-only / Fill-or-Kill
        outcomes are order statuses such as `post_only_rejected`, not
        rejections.)

        parameters, unparseable body, invalid signature, or a domain pre-check).

        action rate), or `open_orders_limit` (resting open-order cap).
