message: |
  Replace `signInWithOAuth` with `signInWithSSO` for Google authentication (Supabase).

  Refactor to:
  ```typescript
  const { data, error } = await supabase.auth.signInWithSSO({
    domain: 'miaoda-gg.com',
    options: { redirectTo: window.location.origin },
  });
  if (data?.url) window.open(data.url, '_self');
  ```
  Ensure `window.open` uses `_self` target.
