Thumbnail máy hút bụi để bàn mini

Create a complete vertical 9:16 promotional home-appliance thumbnail/poster, not a plain single image. Use [ảnh người mẫu] as the exact female model reference and [ảnh sản phẩm] as the exact mini desktop vacuum reference. Design a realistic Vietnamese ad thumbnail showing the female model using or presenting the device on a clean desk. Include one hero image, a product close-up, suction-detail panel, size comparison, and 3 small supporting frames showing keyboard cleaning, crumb pickup, and easy handling. Add a bold Vietnamese headline and a short subheadline. Keep it clean, clear, modern, commercial, and easy to understand. No watermark.
