- Improves spacing between consecutive calls
- Only show disclosure button (i.e., ability to expand the card) when
there's actual content
- Fix font size being bigger than the actual thread
- Add gradient overlay to communicate that you can't scroll within the
card (expanding the subagent call will allow that in the near future)

Here's the result of it all, roughly:
