Subject: [PATCH] WIP: Try a toast that counts down before betting

There's some weird timing/React hook error that sometimes allows this thing to bet twice? IDK, my brain is fried trying to understand it.

Also, progress bar that scrolls down might be cooler than a number countdown? See https://www.npmjs.com/package/react-toastify, although the API for that is more unwieldy/less Tailwind-friendly?
