[css-layout-api] Is there any way to access the properties of children of an element that uses display: layout(foo) ?

Regarding this spec: https://github.com/w3c/css-houdini-drafts/blob/main/css-layout-api/EXPLAINER.md

I wonder if there's any way to access child properties during the layout? For example, if some elements in the layout need to be displayed differently, how could we identify and target them? Is it possible?

Whoops I think this seems possible with this part: https://github.com/w3c/css-houdini-drafts/blob/main/css-layout-api/EXPLAINER.md#querying-style

At first I thought we could only query the parent's styles.

It's not clear how to pass data to a layout fragment - especially since the spec seems to mention data as being part of the constraints but it only appears in the explainer under breakToken.
