Reduced motion spinner

Howdy! Have we considered a reduced motion spinner for a11y reasons?

Poked around for a few minutes and saw that [bootstrap](https://getbootstrap.com/docs/5.0/components/spinners/) slows theirs down and [fluent ui](https://react.fluentui.dev/?path=/docs/components-spinner--docs) changes it from a momentum whiz-bang thing to a slow, linear animation.
