Afterpin, a 24-hour exhibit with one card and a closing flap

Field notes

The folio treats the browser’s local date as an exhibition room: a flap opens, one card goes under a steel clip, and the day closes at midnight. Visitors can lift and replace the card before closing, but prior dates remain sealed. The page also supplies a downloadable ZIP containing profile assets, campaign illustrations, and an independently titled article. A shared wall and on-chain registry are identified as future work rather than functioning features.
