Generate a vertical 3:4 high-definition commercial advertising poster, a single image — no collage, no multi-panel grid. Theme: a new-product promotion poster for [product type]. This is an original fictional brand ad; do not include any real brand logo. Brand name: [brand name] Product name: [product name] Giant headline: [main title, e.g. VISION / RUN / RIDE / ACTION] Subtitle: [a short slogan] Color scheme: [main color + secondary color + accent color] The overall style is a "product-promotion giant-typography perspective poster"; it should look like the key visual of an official brand campaign, with a commercial-ad feel, strong layout design, youthful energy, a product-launch vibe, and visual impact. [Core composition] The subject is [the product], which must be sharp, refined, like a hero product in an ad. Depending on the product type, add a suitable figure or usage scene, e.g.: phone model, runner, rider, skater, athlete, outdoor enthusiast. The pose should be natural and dynamic, with a real spatial relationship between product and figure. [Giant typography in perspective] The main title [main title] must be the core visual backbone of the image, in an oversized bold sans-serif typeface, occupying the main space. The text cannot be just an ordinary title; it must become the spatial structure of the scene — a backdrop wall, a ground-level track, a highway, a ramp, a motion trajectory, or a futuristic installation. The figure and product must sit within this giant-letter space, forming real front/back relationships, occlusion, contact shadows, and perspective depth. [Formal poster information system] The image needs a complete hierarchy of brand-advertising information; avoid being too empty. At the top, add the brand name and small NEW RELEASE / PRODUCT CAMPAIGN text. On the sides, add vertical small text, a series number, a product code, or a campaign number. Near the product, add 3–5 feature selling-point tags, e.g.: [selling point 1][selling point 2][selling point 3][selling point 4]. At the bottom, set a formal advertising info bar with product name, slogan, release date, key specs, small credits, thin dividing lines, and a decorative barcode or numbering. The layout should be refined, restrained, with a real brand-guideline feel. Small text can be decorative micro typography and need not be fully legible, but the brand name, product name, and main title must be clear. [Image quality] High-definition and sharp, commercial-photography quality, real materials, accurate perspective, clear product, natural figure, unified lighting and shadow. Overall like a genuinely released product campaign poster, suitable for phones, digital devices, running shoes, motorcycles, sports brands, and events. [Avoid] No collage, no multi-image combination, no real brand logos, no cheap e-commerce image, no ordinary stock photo, no complex cluttered background, no cartoon feel, don't make the product too small, and don't turn the main title into an ordinary flat headline.
