  "type": "https://docs.atlas.ilionx.dev/errors/UNAUTHORIZED",  "title": "Unauthorized",  "status": 401,  "detail": "Authentication is required or the credentials provided are invalid.",  "instance": "/v1/…",  "errorCode": "UNAUTHORIZED"}

Branch on errorCode, not on detail: the code is stable, the wording may change.
