Stats Preview Card -- Tailwind, Mobile-first

Mostly went smooth, except for setting the background images. I got something to work, but it's a hack and I had to use an inline scoped style tag for media queries.

If anyone can look at my code and let me know a better way to set the background images with Tailwind, I'd really like to know. (FWIW, I don't hate Tailwind anymore but I don't love it either. I could have done this project twice as fast with regular CSS.)
