Generate a detail page for a children's insulated straw cup based on the provided white-background product image. The product originally had no brand information, so no brand name, slogan, logo, capacity, or numeric text were added. The painting uses light oatmeal color and soft cream white, with the top aligned to the left and a large bold black font inscribed "Layer Layer Insulation / Warm Travel." On the right side of the middle section, a partial explosion structure is used to display the lid, straw, and the gap between the inner and outer layers; The product maintains a round, cute, and pink-apricot detail. On the left side, two small rounded corner instruction cards are displayed: "Warm-Locked Cup Mouth" and "Built-in Insulation Layer," each containing a small cross-sectional material diagram and two lines of neutral description. At the bottom, a minimalist curve area is placed, with orange and gray smooth lines representing the "thermos cup" and "basic water cup," without writing the time or temperature values. The font uses a rounded yet crisp modern black font, with cards and smooth curved edges. Do not display child figures, real detection data, original image brands, footnotes, watermarks, overlapping text, or low-definition icons.
