Google account login always fails when using direct Vercel deployment link (https://<gibberish>.vercel.app/)

Signing in through the Vercel deployment link always redirects you to the primary portfolio link's OAuth sign-in error.

Signing in again (like the error page suggests) works, but going to the Vercel deployment link consistently errors out. I think this could be because of HTTP referrals or disabling third-party cookies.

This is probably because the Vercel deployment link is not whitelisted as a valid domain to sign in via Oauth from.
