Based on the provided white background product images, generate a detailed poster for the e-commerce page of a children's cooling sunscreen jacket. The upper half depicts a clear seaside scene, with a child wearing a light blue hooded jacket, leaning sideways and smiling in the wind, with a background of a light blue sky, coastline, and sand; The clothing zipper and partial piping are clearly visible in the sunlight. The lower half is dominated by wave-patterned fabric textures in the same color family, creating a fresh and breathable visual impression. Layout: In the upper right, two lines of white oversized numeric titles read "Cool Touch / Light Summer"; The middle section uses a diagonal wave divider to connect the figure's scene with the fabric in close-up. On the right side of the wave area, a white enlarged title reads "Cool to the Touch," while the left side lists two short sentences highlighting the experience. At the bottom, there is a set of light blue semi-transparent comparison bars, including two labels and a simple progress bar, without using real metrics or values. Rewrite the copy: Main title "Cool Touch / Light Summer"; The main title "Cool to the Touch"; Short phrases like "lightweight fabric, comfortable in the wind" and "daily sun protection makes travel easier"; Comparison bar labels "Cool Skin" and "Light and Breathable." Product Performance: White background product images are used as children's clothing styles, maintaining light blue hoodies, delicate textures, and light silhouettes, with fine-tuning zipper and piping colors. The product originally contains brand information, so only "MOCKUP" and "EMBRACE YOUR BEAUTY, UNLEASH YOUR POWER" appear on the clothing, with no other logos, parameters, or small print. The font uses smooth and full sans serifs, with headings that are especially thick and have slight highlighted edges, and the main text is of medium weight; All text should be left in clear areas to avoid covering the child's face. Curves, icons, and contrast bars have smooth edges, without obvious shadows, standard magnifications, detection data, prices, watermarks, or screenshot edges.
