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.)
