Photographers pay 0.01 USDC once, in-page, and the rights clearing seal is written on-chain for them — no funded host-chain wallet, no subscription, just a payment log that ends in a real transaction.

Drives the UI as
a numbered payment log running from 402 challenge to settled USDC to the host-chain anchor tx, every hash a clickable explorer link
