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`,
`price_outside_bounds`, `position_not_found`,
`invalid_margin_mode`, `invalid_margin_amount`,
`margin_below_required_initial`, `account_liquidating`,
`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.)
