{
  "type": "https://docs.atlas.ilionx.dev/errors/UNSUPPORTED_MEDIA_TYPE",  "title": "Unsupported Media Type",  "status": 415,  "detail": "The request body format is not supported by this endpoint.",  "instance": "/v1/…",  "errorCode": "UNSUPPORTED_MEDIA_TYPE"}

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