Nostro.at uses the njump.me code, so the logic it is exactly the same :)
Does Njump.me give you any rendering problem?

In iMessages below. Looks like they are both the same. Trying to share

As said nostr.at uses njump.me original code (https://github.com/fiatjaf/njump), so it is absolutely normal that they are the same. I was just trying to understand if you use the first because njump,me gives you problems, but it doesn't seem the case.
Oh gotcha 🤙
