Two errands before a quarter-close celebration. The pen shop speaks Shopify's agent protocol, so Esan searches it and builds a cart directly. The bakery has no API at all, so Esan opens a browser, finds the cake, fills the order and picks the collection slot, then stops at the terms checkbox and hands over the live page, because that box is the owner's to tick. One click later it carries on in the same session and reads back the confirmation number. The cake is real.
