OK I've created a simple sample page for making NIP-96 uploads the way I am in my larger project. I've also included a variation that generates the Auth header differently (according to NIP-96 where it contradicts NIP-98). Not sure what I'm doing wrong here...

You can run it with ``` npx webpack serve -c webpack.dev.js ``` the "My version" checkbox activates the variant upload, rather than only using stock nostr-tools functions. @nostr.build any ideas? To the extent I am able as a non-web dev who's very unfamiliar with modern PHP, reviewing the nostr.build source it wasn't obvious to me what is going wrong either. @Quentin I get approximately the same 400 response with nostrcheck, does anything jump out at you? I appreciate any help y'all can give, and sorry for the noise. At least, if you're aware of clients that work with your nip96 endpoints specifically, I'd love to see them and compare...

Hodlbod confirmed he's using nip-96 after all, so I can reference his code to figure out what's going wrong on my end. Don't waste your time reading this garbage until I've looked over his code lol
