Re: [csswg-drafts] New `border-radius` value for perfectly matching nested radii (#7707)

> Though as I said, `overflow: clip; overflow-clip-margin: content-box` seems a better solution in most cases.

For visual parity you could just use a thick border, which might even trump the overflow clip approach. 
There is a common use case where you would have an element partially moved outside the card container to highlight it. Like so: https://codepen.io/dutchcelt/pen/ExLKZGe

The thick border is messy and overflow clip is a bit too restrictive. I think the case to have a simple unintrusive solution for this is clear. 

```css
.panel {
  border-radius: 24px;
  container: panel / size;
}
.content {
  border-radius: follow follow 0 0; /* default is parent */
  border-radius-target:  panel; /* could be child element */
}
```
I've suggested `follow`, but `fit-parent` or `nearest-parent`/`nearest-child` would also work well.
