Eyyy tasty! There were some issues with conflicting styles with the main app, but I think we got it!
Scoping Chakra's CSS reset was a big deal to not accidentally overwrite the app's own styles lol, and we had to solve a specificity problem for that, thanks Aria for the :where tip!! <3
This is a bit more standard, and has the bonus of being compatible with Devise, which is using `flash[:notice]` and so its flashes were coming out unstyled, oops!
