  // openai-compatible provider appends /chat/completions to baseURL, so
  // baseURL must be the prefix *without* the /chat/completions suffix:
  //   correct:   http://localhost:8890/v1         -> POST /v1/chat/completions

  // The server now tolerates the wrong form via alias routes, but configure
  // the correct prefix to avoid the extra hop.
