```
public final class FBLoginSSOLauncher

                    
```
Launches the FBLoginSSO activity and handles the result via AndroidX ActivityResult APIs.
This class owns the full lifecycle: launching the SSO activity, receiving the result via ActivityResultLauncher, parsing raw bundle extras into tokens, and delegating to LoginManager.onActivityResult for token persistence and callback dispatch.
Must be instantiated during or before the activity's CREATED lifecycle state (i.e., early in onCreate) because registerForActivityResult requires it.
