Custom domains are finally working on my side project

Spent the last couple days getting this right: connect your own domain, verify DNS, get SSL issued automatically, then your short links go out under your brand instead of the default domain. Small feature on paper. Felt like a real milestone though — it's the difference between "urldn.com/abc123" and "link.yourbrand.com/abc123," and that's the kind of detail that makes a side project start to feel like an actual product instead of a demo. Still building, still finding bugs. Onward.
