Create a clean, modern mobile UI for a food delivery checkout screen in Kazakhstan (like Glovo/Choco).
Key components: 1. Top Header: "Оформление заказа" with a back icon. 2. Address Section: Active address "Астана, пр. Мангилик Ел, 25", editable fields for apartment/floor/entrance, and a toggle for "Передать курьеру" / "Оставить у двери". 3. Payment Method: Clickable selector between Kaspi Pay (marked as Popular/Fast), Bank Card, and Cash. 4. Tips Section: Selectable tip amounts (0 ₸, 200 ₸, 500 ₸, 1000 ₸). 5. Order Items: Collapsible list showing items (e.g., 1x Бургер, 1x Кола). 6. Price Summary: Subtotal, delivery fee, service fee, and Total price in Kazakhstani Tenge (₸). 7. Sticky Bottom Bar: Fixed container at bottom with total sum (e.g. "4 500 ₸") and a large primary button "Оплатить и заказать".
Interactivity: - Payment methods and tips must be clickable and toggle visually. - Clicking "Оплатить и заказать" should trigger a simple success modal "Заказ принят!".
