An iPhone mockup in portrait mode showing a multi-step checkout flow at the payment step, in a light-mode e-commerce app. At the top, a step-progress indicator shows three steps: "Cart" (check mark, completed), "Shipping" (check mark, completed), "Payment" (active, blue). Below, a section header "Payment Method" contains two selectable cards: the active one shows a credit card form with masked fields "•••• •••• •••• 4242", expiry "09/27", and a CVV dot-mask field; a small Visa logo sits in the card's corner. The second card is an unselected "Pay with Wallet" option showing a balance "$42.50". Below, a collapsible "Order Summary" accordion shows item thumbnails, names, and subtotal "$189.00", discount "-$40.00", shipping "Free", total "$149.00" in bold. A sticky bottom bar has a full-width deep blue button labeled "Place Order — $149.00" and a padlock icon for trust. Color palette: white background, deep blue #1A3DDB CTA, light gray borders, green checkmarks. Tight, trust-signaling layout.
