Vouch for a specific, real thing about someone — not a star
rating, a concrete claim. This builds a real
NIP-01
event (kind 3300, persona's own attestation shape),
signs it with window.nostr (any NIP-07 signer — the
persona extension or another), and
publishes it to real public relays. There's no separate "send
this to them" step — publishing to a relay is the
delivery; anyone can look it up by querying for events tagging
that pubkey, same as the lookup below does.

Anyone can mint a new one; no registry required.
