Based on the provided white background product image, generate a detailed poster for the men's lightweight down jacket e-commerce page. The overall design is a warm white promotional board with fine paper textures, centered on a male model wearing a light gray-blue down jacket and carrying a lightweight hiking bag; Three small cards with white backgrounds and borders are placed around the edges, displaying different colors or close-up wearing effects. Layout: Upper left is decorated with a large gold-brown numeric designation and two lines of black-gray titles reading "Light Warm Zone / On-the-Go Insulation"; In the upper right is a vertical small card and two lines of blue-black short sentences; The lower left is a small card, with two lines of dark brown accents below; The bottom right is a product detail card. The central figure occupies the main area, and the cards do not press down on the person's face or the main body of the clothing. Only the minimalist brand area remains at the bottom. Rewrite the copy: Main title "Light Warm Zoning / On-the-Go Insulation"; On the right, "Comfortable Layering / Easy Travel"; Bottom left: "Lightweight Windproof / Comfortable for Daily Wear"; The bottom subtitle is "Lightweight Down Jacket." Product performance: Based on the graphite blue quilted jacket shown in the white background product image, it maintains a stand-up collar, horizontal quilting, and lightweight silhouette, allowing adjustment of quilting rhythm, color brightness, and posture. The product originally contains brand information, so only "MOCKUP" and "EMBRACE YOUR BEAUTY, UNLEASH YOUR POWER" are used, without any other brands or fine annotations. The font is modern outdoor style sans-serific, with extra-large numbers but not exceeding the title area. The title is half bold to bold, left-aligned, and helps with standard text. The card frame is thin and straight, with text that does not overlap with the product; No description of down content, parameters, prices, QR codes, watermarks, or footers.
