In the Next.js Custom UI/Kratos Tutorial, why is the

ORY_KRATOS_URL

using port 4455 (Selfservive UI) instead of 4433 (Public API)? From my perspective, the Next.js UI should be able to straight up replace the selfservice UI. Does the self-service UI also handle the

/self-service/

endpoints? Edit: Here's the tutorial https://www.ory.sh/nextjs-authentication-spa-custom-flows-open-source/ Edit2: I think it's a typo because in the README for the repo, the port is 4433.
