Errors are RFC 9457 `application/problem+json` with `code`, `detail`, and `hint`. Pin `API-Version: 1`. Breaking changes will ship as `/api/v2` with `Deprecation` and `Sunset` headers first.

HTML pages honor `Accept: text/markdown`. Unknown HTML paths return HTTP 404 plus a markdown recovery body when you ask for `text/markdown`.
