ownerState type safety in variants

[pushys]

This would allow to type safely use ownerState's properties in styled's variants without providing a callback.

The problem is that now the example below works as intended (a new class name is correctly applied when rounded is true), but the compiler complains because it doesn't know anything about ownerState's type (only props overall).

import { styled } from '@pigment-css/react';

const StyledDiv = styled('div')<{ ownerState: { rounded: boolean } }>(
  {
    backgroundColor: 'blue',
    variants: [
      { props: { rounded: true }, style: { borderRadius: 8 } },
    ],
  },
);

function App() {
  return <StyledDiv ownerState={{ rounded: true }}>div</StyledDiv>;
}

export default App;

Or maybe I misunderstood something and ownerState isn't supposed to be used without a callback.

• I have followed (at least) the PR section of the contributing guide.

I am wondering if ownerState is needed at all. According to docs you can use props just so https://github.com/mui/pigment-css?tab=readme-ov-file#styling-based-on-props
