The Naut chip that's sat quiet in the corner of the HUD finally does something: press it and the Nauts Shop opens, right there over the water, no trip to the Berth required. A handful of pack sizes sit on the counter, and the price of each is set at checkout — never guessed at, never hardcoded, always the same number Stripe actually charges.
Checkout itself happens on Stripe's own hosted page. The game never sees a card number, and once a purchase clears the Nauts land in your account and follow you to any device you sign into — buy on a phone, keep diving on a desktop, same wallet either way. If the credit is a few seconds behind the redirect back to the water, nothing is lost: it arrives automatically the next time you sign in.
What doesn't change: Nauts buy speed, never access. They can stamp out a Warehouse row, cover a class re-calibration, or close out a part you're a few pieces short of — every one of those is something you've already earned the right to reach, just faster. The rarest tier of anything in the Ledger is still earned only by diving for it, same as day one.
