Discuss the best way to add additional component styles to polaris

[sarahill]

There's a proposal to add variants to some polaris components with magic styling applied - Github issue. Magic is starting to be used throughout the admin so it could make sense to bring these closer to Polaris.

The team working on these is looking for guidance and support.

Discussion points:

• What's the best way to add additional component styles to polaris?
  • Component level theming
  • Component variants
