* Add spacing rhythm system, add the rest of the base colors
* Add styles for the ActivityCard
* Use the new ActivityCard in the orders panel
* Update text color & size
* Disable timestamped test (string changes based on date)

The difference between gap and gap-med is not intuitive, so let’s switch to -small, and change -small to -smallest.

* Move tabindex to <Section /> and add aria-label to the panel
* move role and aria-label to div component
