Affiche publicitaire de produit avec titre géant en perspective

Generate a high-definition commercial ad poster in vertical 3:4, a single image, no collage. The theme is a [product type] new-product promo poster, an original fictional brand, no real brand logos. Brand name: [brand name] Product name: [product name] Giant main headline: [PLAY / FOLD / CREATE / FOCUS etc.] Subtitle: [a one-line slogan] Color scheme: [main color + secondary color + accent color] Character type: [gamer / creator / tech-styled model / product user] Selling points: [point 1], [point 2], [point 3], [point 4] The overall style is a "digital-product giant-typography perspective campaign poster." The product must be clearly shown as the hero product, with accurate proportions, realistic materials, and refined details. The character should have a big ad-campaign feel and a clear pose, and may hold, display, wear, or be using the product. The main headline [giant letters] uses an oversized bold sans-serif typeface, occupying most of the frame. The text should become the brand backdrop wall, the perspective stage, the tech space, the floor corridor, or the product runway, with obvious one-point or slanted perspective, clearly legible and visually striking. The character, product, and giant text must share the same spatial logic, with depth relationships, occlusion, contact shadows, and unified lighting. Add a formal brand advertising information system: brand name at the top, small campaign text in the upper-right corner, vertical side information, feature icons beside the product, and a bottom info bar containing product name, subtitle, release date, specs, small credits, thin lines, and a barcode. The whole should be crisp in high definition, high-contrast, with a tech-advertising feel, like a genuinely released digital-brand campaign poster. Avoid: collage, real brand logos, cheap e-commerce look, product distortion, fake faces, cluttered background, unclear headline, too-weak perspective.
