[Refining the core](https://joshcusick.substack.com/p/design-systems-should-do-less)

### Approach
- Audit existing usage
- Quantify the problems: number of instances the component is being used in, the state of misconfiguration it's in
- Explore viable solutions.
- Plan fast-track: high-impact, low effort -- What can we do, how much time will it take, and how much of an impact will it have? Scope accordingly.
