This turns on a lint rule to require display names for all of our components, which makes it a lot easier to find your way around the component tree in React's dev tools.
As a first step towards adopting the Compound design system and the new Element Call designs, this pulls in Compound's color tokens and applies them to all existing components. I've tried to choose tokens based on the semantics of where they're used, but in some cases, where the new and old design systems differ in semantics, it was necessary to choose tokens based on their resulting color. These hacks can be removed as we implement more of the new designs.
There were a set of environment variables that we used for custom themes, but Compound has way too many design tokens for that approach to still be a good idea, so I decided to replace them all with a single environment variable that just lets you write arbitrary custom CSS.
by fixing the cause rather than the symptom: this upgrades the code to use the new, recommended JSX transform mode of React 17+, which no longer requires you to import React manually just to write JSX.
