fix payload
# Fix: Stripe payment intent rejected on /checkout

Context:
- Route: /checkout
- Failing step: "Click Pay" → expected redirect to /success
- Actual: 402 from POST /api/stripe/intent
- Persona: returning_customer (US, card 4242…)

Likely cause:
  createPaymentIntent() is missing `automatic_payment_methods`
  on the server, so Stripe rejects the confirm() call.

Suggested patch (server/stripe.ts):
  const intent = await stripe.paymentIntents.create({
    amount, currency: "usd",
  + automatic_payment_methods: { enabled: true },
  });

Re-run: assertive run checkout-flow --persona returning_customer
