Does it need the Shopify connection?

No. Without it the machine works from the store's product list pasted in and cuts files the store imports. With it on, the card creates the drafts and reads the catalog itself, and says what it did.

Will it publish for me?

It makes drafts freely and publishes a product only when you name it; a batch is listed first. That is the law on the face.

Where do prices come from?

From you, on the ladder or off it. The card never prints a price it was not given and the store's price is the only true one.

Can it attach the files?

No — that door is the app's and yours. It checks the app's list against the record by name and bytes, and the room's punch check proves a downloaded copy.

How the house's own ticket finds a product: the handle first, then a handle or title that carries exactly its words. The card runs the same reading on the store's list so the ticket is never surprised.

No. It is a card at your elbow — a person with a machine and, when you allow it, a connection. It stores nothing, runs no server and holds no key of its own.

CITE THIS CARDTHE SITE CART, Edition 1. Lund Studio LLC, Westminster, Colorado. https://lundr.tech/?view=site-cart-card. Punch D41F885A5A5534CEB918DB4B. Retrieved 2026-10-10.

What it is.

A site-wide cart for a Shopify theme: one request queue, optimistic quantities that roll back in the store's own words, adds never retried blindly, titles and gift dedications escaped and carried as order attributes, an access code carried to checkout, cross-tab sync, a focus trap, the shop's money format, every add-to-cart form taken over in place, and a server-rendered cart page that works with no script at all. Thirty-one browser checks at four widths against a stand-in for the cart API; never yet run on a real store, and it says so. Named for its job; its working name waits on counsel.

The app itself goes inside the packet: the six theme files (the engine, the styles, the snippet, the cart template) with the stand-in and its tests, from its chat (Sep 18 2026). Until it is sealed in, app/README.md says what goes there; seal.py writes it into the manifest without touching the door, so the punch stays true.

Its laws, written into the card.

Read the source before you change it; never generate what the app already has.
Prove every change by running the app; report what you checked and what you did not.
No key, token or password is ever written into the app or this card.
A card instructs an AI you operate; results depend on your model, your files and your judgement.

How it works, once your AI has it.

ON EVERY DOOR · A CARD FOR YOUR AI, A FILE FOR YOUR COMPUTER

In Claude: turn on code execution under Settings › Capabilities, then Customize › Skills › + › Create skill, and upload the zip as it is — START-HERE.md in the box walks you through it, and tells you how to keep the ledger. In ChatGPT, Gemini and the rest: a Project, a GPT or a Gem with the card’s files attached and the short door in the box pasted as its instructions. The words run anywhere an AI reads Markdown; the machines run wherever the host runs Python. Witnessed in Claude only. The host marks →

ONE PAYMENT · NOTHING RENEWS ITSELF

OFFLINE · ONE LICENCE · PUNCH-CHECKABLE · THE STANDARD

One payment. The file is yours to keep and keeps working at its edition; new editions issued in the year after you buy reach you by email as replacement files. Tax is added at checkout where it applies. Nothing auto-renews.

ONE PAYMENT — NOTHING RENEWS ITSELF. CHECKOUT IS SHOPIFY’S OWN; YOUR CARD COMES BY EMAIL AFTER IT.
