Yeah, it handles Nostr entities in a sensible manner, basically.

You can see how that works in my latest PR. The Nostr Markup logic is actually complex. That's how the problem of the disappearing links came about. I'm not disappearing them, with my parser, I just add an internal link behind them, and then the user is free to choose.

Sometimes external links are broken, after all, or you're someplace with slow Internet and avoiding websockets.
