👨‍💼 We now have a counter inside the App component and every time that count is incremented, we trigger a rerender of the Footer component! Have we lost the ability to take advantage of React's element optimization? No!

Instead of accepting the color via props, we can place it in a context provider that the Footer can consume. And with that, the footer no longer accepts any dynamic props so we can move it outside the App component again, which means the only way it can be rerendered is if the context changes (which is exactly what we want).

When you're done, make certain that the Footer only rerenders when the color changes and not when the counters are incremented.
