Domains
Branded redirect domains attached to the app. Reusable by any client or code.
Add a domain
After adding, set DNS at the registrar: a CNAME to cname.vercel-dns.com, or an A record to 76.76.21.21 (you cannot have both for the same host). Then Re-check. A domain shows pending until DNS resolves to Vercel.
