hackclub/dns ? reverse-engineered prompt

Build me a simple GitHub based DNS management setup for Hack Club, where each domain has its own YAML file and people can add or edit subdomains without needing to understand a lot of DNS stuff.

I want it to work with OctoDNS, include clear docs for adding a new subdomain, and handle the common cases like CNAME, A, and TXT records. Make sure the repo is organized so changes are easy to review in pull requests, and that the DNS config is checked before deploys. If it makes sense, add a lightweight helper page or form for adding a subdomain more easily, since the README mentions a website at dns.hackclub.com.

Keep the experience friendly for people who are only making a small change, but still safe for bigger edits. Also make sure the instructions explain when someone should use the website versus a pull request.
