Poster quảng cáo bình giữ nhiệt cho mẹ bỉm

Create a complete vertical 9:16 promotional thumbnail/poster, not a plain single image. Use [ảnh người mẫu] as the exact model reference and [ảnh sản phẩm] as the exact baby-mom product reference, such as a thermal bottle, water bottle, or useful parenting accessory. Design a Vietnamese social media poster for a practical mother-and-baby product. Show a large hero image of the model holding or presenting the product, with supporting mini panels that highlight convenience, portability, or daily use. Include a bold headline, a short subheadline, benefit icons, and a clean informative layout that is still highly commercial. Preserve the model identity and preserve the product shape, cap, color, material, and design details accurately. Make the poster friendly, soft, trustworthy, and sales-oriented for TikTok, Reels, Facebook, and Shopee. Use clear readable Vietnamese text, balanced layout, and no clutter. No watermark, no anatomy errors, no unreadable text.
