First "mint usernames" commit on caw-front

❶ On the official front-end repo cawdevelopment/caw-front, a commit titled "feat : mint usernames" landed with author date 2022-12-11 (sha 910ccf46…). ❷ Nearby commits add a minted-username page and, on Dec 21, the ability to change usernames. ❸ This is the code-side date for NFT-username work — earlier and more precise than the community's "Jan 2023 Goerli experiments" note. Author date on caw-front (not a later-rebased repo) is the source of truth here.
