Overall, this is amazing work! One small request I have is that the the grid / flex styling be more consistent across action input stages. For example, the intake and eject screen is arranged vertically and doesn't fill the screen, while the scoring screen buttons fill the screen.

Also, unrelated, but you should probably name branches more specifically in the future, there are likely to be several styling PRs going forward : )

I'm so sorry, I should have been clearer, I prefer when the buttons take up as much of the screen as possible.

As in like, this is good and I think that other screens should have buttons that take up this much space as well.

I rolled back some commits, so git forced me to make a new branch because apparently rewriting git history is bad practice :P
So this PR is on #9
