STRIPE SANDBOX
Test checkout without real money.
A hidden $0.50 Stripe Checkout Test Item has been added. V11 now creates a pending CMBTrades order before Stripe opens, then verifies payment and marks that order paid when checkout succeeds.
V11 end-to-end test
Your Stripe test key is already stored in Supabase. Run checkout, complete the sandbox payment, and the success page should verify it and place a TEST order in the Orders queue.
Once that secret is set, add the test item to the cart, choose checkout, and use a Stripe test card such as 4242 4242 4242 4242 with any future expiration date and any CVC.
