LNURL payments name the merchant: after the pay-params fetch, the metadata's text/identifier (the lightning address) replaces the bech32 blob as the payee's name and address on the amount screen, with the text/plain description as fallback. And when the address is a coinos name — whether it arrived as an lnurl's metadata, a typed [email protected], or an intent — the registrar is asked who owns it and the screen wears their AVATAR via the same profileChip the npub zap flow already uses; the pubkey also lets a NIP-57 zap request attribute to the right person. Lookup is fire-and-forget so the amount screen never waits on it
