this means you can either set a CNAME to [branch.]repo.user.domein (subdomain) or A + AAAA records and a TXT (root)
to point your custom domain at #pixie pages
everything gets checked and you get feedback if something isn't configured correctly yet
I might add an API route for checking a domain too, so you can just fill it in on the main pixie.homes page and see what you have to (still) set up
