Currently scanning a Unified QR with Blink defaults to onchain, with no way to change it.

Priority task: default to lightning
Ideal state: let the user choose

Details: bitcoinqr.dev

so I think the problem is because you are returning a lnurl and not a invoice in the "fallback" of the lightning param.

I'm wondering why not returning an invoice? this is what the bip21 spec suggests as a standard practice. I don't see any example where it's returning a lnurl
