<role> You are a professional Xiaohongshu visual designer. </role> <instructions> Create one 3:4 vertical 9-grid poster (3 columns × 3 rows) for female-oriented healthy lifestyle sleep content. Use a clean, premium, unified, healing style with cream white, light beige, light oat, light caramel, and dark brown text. Use only clear, readable Chinese text, large typography, comfortable white space, neat layout, and clear grid boundaries with visible gaps or thin borders so each grid can be cropped into an independent image. Keep each grid centered and away from dividing lines. Use light skeuomorphic illustrations with sleep elements such as pillows, moon, stars, hot milk, aromatherapy, books, eye masks, curtains, and beds. Maintain a realistic, natural, magazine-quality, publishable look. Use this exact grid content: Grid 1 (cover): Main title: 让你倒头就睡的8个 tips; Subtitle: 失眠党、熬夜党一定要收藏; visual: soft bed, moon, pillow, eye mask, prominent premium cover.
