Refine 404 styles

See #311

Doesn't try to fix these, since they'll be easier to focus on in separate PRs, after this is merged.

• the negative offset on the "oops" element. I ran into a bunch of weird overflow issues
• the home-link block empty output. seems like a recent regression, it's happening on trunk, and the cause isn't obvious. maybe related to recent gutenberg release.

Thanks @iandunn, I can't see it properly because my testing env is somehow stealing some space below the header, but besides the "Oops" element, the screenshots looks accurate 👍

I think you're behind on a Gutenberg update, or you've got it deactivated locally.

Overall this looks good, just a few comments, mostly accessibility-adjacent.

The "homepage" link here should be using var(--wp--preset--color--blue-3);, and the search input could use a focus state (I don't know if there's one designed, @beafialho).

Ah, you're right, thanks!

I had Git and SVN checkouts of it for various reasons, but accidentally updated it w/ wp-cli, which left the folder empty except for node_modules.

I think the only remaining thing is possibly the focus state. I'm going to merge this to make it easier to start on the follow-up PRs, and the focus state can be done in one of those based on Beatriz's feedback.
