Missing CSS when using design system

I’ve written a custom admin plugin for my client which adds a few pages to the admin and settings. I’m using the Strapi Design System as recommended.

The problem is that there is no styling for lists, or a few other basic HTML elements. It looks like the stylesheets used by the admin do a full reset and so anything not directly supported by the design system (which lists are not, afaict)

What’s the cleanest way to add properly styled lists to my admin interface? Should I use styled-components which the design system depends on (I’ve never used it, but it seems like it should do most of what I need.
