Poster mã QR đặt lịch dán cửa tiệm

Design a clean, modern window poster, vertical 2:3 (print size 11x17 inch), for a [nail salon / hair salon] named "[Business name]". Center: a large EMPTY white square with rounded corners and a thin gold border, labeled area for a QR code (leave it completely blank — I will place my real QR code there). Above the square: headline "Book Your Appointment" and below it in Vietnamese "Quét mã để đặt lịch". Below the square: three small friendly line icons in a row (phone camera, calendar, sparkle) with empty space under each for short steps. Background: soft blush pink to cream gradient with delicate botanical line art in the corners, minimal and elegant, high contrast so it is readable from 2 meters away through glass. Bottom strip: empty band for opening hours and phone number. No fake QR code, no prices, no logos. (Ghi chú: AI KHÔNG tạo được mã QR dùng thật. Tạo mã QR từ link đặt lịch thật bằng Canva QR code, đặt vào ô trống, quét thử bằng 2 điện thoại trước khi in.)
