Looks good, only a few minor suggestions you are free to do with what you want. there's quite a lot of links in snippet comments like https://storybook.js.org/docs/7.0/angular/... that looks off to me, but maybe they're correct.

Thanks for taking on this item; left some items for you to look into once you have a moment. I'll take another pass later on and if nothing arises approve it so that we can have it documented.

Can you confirm that this image is accurate? I suspect this was documented there as a placeholder and should be updated, as it was captured from a previous example and should instead align with the above example.

Good eye! Looks like it's always been wrong. 😅

I resolved this by simply re-using the List-based snippet and screenshot.

Let's go with it then.
