/**
* @deprecated Use {@link useAuiState} to select and narrow `s.part`.
* Return `null` for optional rendering. Do not throw inside the selector:
* selectors run inside `useSyncExternalStore`'s `getSnapshot`, so a transient
* part mismatch during thread switches can unmount the React root.
*
* @example
* ```tsx
* const part = useAuiState((s) =>
*   s.part.type === "data" && (!name || s.part.name === name)
*     ? s.part
*     : null,
* );
* ```
*
* See the {@link https://assistant-ui.com/docs/migrations/v0-12 migration guide}.
