Understand the concept
A domain name is a human-friendly label. DNS records help clients discover where to connect. A CNAME points a hostname at another hostname; DNS resolution is not the same as HTTP content delivery.
For this website, Cloudflare manages the public hostname and directs it through a tunnel. That arrangement avoids publishing a private home address as the website origin.

Draw the journey: visitor → DNS → Cloudflare → tunnel → Nginx.
