End-to-end: new member journey from sign-up to cancellation

Interview scenario

"Our highest-value flow is a new member who signs up, saves things, buys with a member coupon and later cancels. Automate it end to end: sign up in the UI, seed the wishlist through the API, move an item to the bag and add another in the UI, apply NEWUSER, pay to a saved address created through the API, then verify the order through the API and cancel it in the UI."

Acceptance criteria

1. UI: create an account with a unique email (Create an account link, then Name, Mobile, Email, Password). API: GET /api/me returns that email.
2. API: POST /api/wishlist for productId 106. UI: on the wishlist choose size S and Move to bag; open product 104, pick size M, add to bag; in the bag set its quantity to 2 and apply NEWUSER, asserting the coupon message.
3. API: GET /api/bag totals must equal what the bag page shows (count 3, Total Amount). POST /api/addresses for a saved address.
4. UI: PLACE ORDER, choose the saved address and Cash on delivery, CONFIRM ORDER and assert the confirmation. API: GET /api/orders has that order with status confirmed and the same total. UI: open the order from My Orders, Cancel order, and assert the status is cancelled; API agrees.
