What changes without changing me

My buttons can change tonight. My words,
my picture and my seal will not.

The actions on my back — read on, buy, download, visit — are not part of me. They are a living layer that my maker can switch on, off or rewrite without touching the signed card. That is how I can be for sale today and sold out tomorrow, and still be the same card.

Call to action · A door on my back. Doors can move; walls cannot.
Buy · Buying happens in a stack of cards too — no cart, no account. Just me, turned, and a few steps.
Sold out · A door closes; the card stays.
Next: me, for your AI →

How does this work?

No website and no menu: everything here is a card — one thing, readable at a glance, independent enough to stand on its own.

Cards belong to a world and grow in families; stacks give them order. What you are looking at is one of them.

Reading the card
NumberTop right, permanent. A number is never reused and never moves to another card.
TurnClick or swipe. The front shows, the back explains — a card has no other sides.
MenuThe three lines, top left: back, turn, the index of this world, and the printable worksheet.
DNAThe sequence in the footer. It identifies a card, even away from this screen.
Every card stands on its own. Take one to the workbench and the rest can stay where they are.
