The checkout request carries product IDs, quantities, the delivery choice and the language, and nothing else. The server looks each ID up in its own catalogue, refuses an unknown product or a quantity that is not a whole number from 1 to 99, and works out the subtotal and the shipping from its own prices. An edited request can change what is ordered, never what it costs. Line items are built per request in Australian cents rather than registered in Stripe as fixed prices, so the site's catalogue is the only place a price lives.

Choosing delivery makes the checkout session collect a shipping address, limited to Australia, and a phone number, and adds A$50 as its own line unless the subtotal has reached A$600. Handover in person collects neither and adds nothing. The choice is written onto the payment and its invoice as the order type, so each payment in the Stripe dashboard says how the bottles are to reach the customer. Invoice creation is switched on, which is what sends the receipt.

Going to Stripe and back is a full page load, so the cart cannot live in React state. It lives in a small store synced with local storage and read through useSyncExternalStore: the server renders an empty cart, the browser restores it after hydration, and a change in one tab reaches the others. What is read back is checked item by item, and a malformed item is dropped on its own instead of breaking the cart. The success page empties it and reads the payment from Stripe on the server, with the secret key in a server-only module. A customer who comes back from Stripe with the back button gets the page from the browser's cache, so the checkout button is reset rather than left saying it is processing.

Whether a visitor has passed is kept in local storage, which the server cannot read, so the server's HTML carries a dark cover in place of the check. A line of script in the head, run before the first paint, marks the page for anyone who has already passed, and CSS removes the cover for them: a returning visitor never sees the check flash up, and a new one never sees the page before it. The opening animation waits for the pass instead of playing out behind the check. Where storage is blocked, the pass holds for the rest of the tab.

Pages are Server Components that say what moves with a data-motion attribute — a heading set a character at a time, a photograph revealed behind a rising edge, an archive photograph that develops, a timeline whose line grows with the scroll, a number that counts up — and a single client hook attaches GSAP to all of them. On a direct visit, anything already on screen is left exactly as the server drew it, so the motion never holds back the largest paint; of the opening animations, only the home page's hero plays. The night timelapse is not preloaded: the HTML shows its first frame, and the video is fetched only for visitors who have not asked for reduced motion.
