- Add @stripe/stripe-js + @stripe/react-stripe-js
- New src/lib/stripe-client.ts: cached loadStripe helper
- New src/actions/billing/retail-payment-intent.ts: server action
that creates a PaymentIntent with automatic_payment_methods
- New src/components/storefront/StripeExpressCheckout.tsx: embedded
ExpressCheckoutElement (Apple Pay, Google Pay, Link, PayPal) +
PaymentElement (card) + hosted-checkout fallback
- /checkout form is now controlled; StripeExpressCheckout reads
name/email/stop from form state and confirms in-page via
stripe.confirmPayment
- /checkout/success handles both ?session_id= and ?payment_intent=
so embedded + hosted flows both land on the same order-creation
page using the pending_checkout sessionStorage payload
- Export StopInfo from CartContext and select 'time' on the stops
fetch so the local Stop shape matches the context's StopInfo
- QuickCartSheet express buttons are visual shortcuts only;
/checkout auto-renders the real Apple Pay / Google Pay buttons
Requires NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY for the embedded path;
if missing the embedded section falls back to the hosted
Stripe Checkout button. npx tsc --noEmit passes.
