To show you can push to z80dev/lemon, add a file named .favz-claim at the top
of its default branch, holding this line:
favz-claim-1791104122-ddcbc1d1b3d80d23ecbd8c21
Then press Check. A pull request works too, once someone who can push merges it.
The code works for 7 days; keep this page or come back with the same link and a new code. We read the file once through GitHub's public API and keep the repo, the GitHub login of whoever committed the file, and the date. Delete the file after. You don't need to claim a repo to get it off Favz: ask for removal, no proof needed.
