what's the easiest way to spin up a customized mint page given an ERC-721/1155 address?

something exactly like what mint.fun had would be perfect

Here’s the repo. It’s meant as a really simple example. You should make your own!

https://github.com/horsefacts/mint-mini-app

Think @horsefacts.eth had an open source mint mini app, unless you were looking for non-FC native

if nothing good exists, maybe I can just make this in a day

Would also like to know this 

Would be great if something like a more customizable mint.fun existed to easily make mint pages on top of any contract (maybe even extended to a mini app too!)
