Constrain type on CardOuterComponent

[davidpmccormick]

What?

In making the view transitions, we conditionally toggle between the CardOuter and CardOuterTransition styled-components. The ElementType I used (so's not to spend more than a day trying to fix it) is generic and a more constrained type would be more useful for catching typing issues.

Why?

Because we use TypeScript and it works best when types are as constrained as possible.

Done when

• [ ] the CardOuterComponent type is more constrained than React.ElementType
