Purchase receipts

Every receipt a purchase ends in, driven with fixed numbers. No purchase is made.

Payment card

A card you fill in. This one is a preview: nothing is minted and nothing is charged.

Payment card — $1 charge

Same card, aimed at the server-priced $1 demo plan. On a test key it takes Stripe's 4242 card with no real money; on a live key it stays a preview until you are signed in.

Payment card — any product

A shop's own price row, minted by the same server door as every other checkout. The block gets its workspace stamped by the page; this demo passes it by hand.
