Create one high-resolution vertical 3:4 commercial campaign poster. Generate a single image, not a collage.

The theme is a launch poster for a new [Product type]. Use an original fictional brand and do not show any real brand logo.

Use a “digital product campaign poster with giant perspective typography” style. The product must appear clearly as the hero product, with accurate proportions, realistic materials, and refined details. The person should feel like a commercial campaign model with a clear pose, such as holding, presenting, wearing, or actively using the product.

Set [Large headline] in oversized bold sans-serif type occupying most of the frame. Turn the typography into a branded backdrop, perspective stage, tech environment, floor passage, or product pathway. Use a strong one-point or slanted perspective, keep the text legible, and create high visual impact. The person, product, and giant lettering must share the same spatial logic, including depth, occlusion, contact shadows, and consistent lighting.

Add a complete brand-advertising information system: brand name at the top, small campaign text at upper right, vertical side information, feature icons beside the product, and a footer containing product name, tagline, launch date, specifications, small credits, fine rules, and a barcode. Keep the image high-resolution, sharp, high-contrast, and technological, like a real digital-brand campaign poster.

Avoid collages, real brand logos, cheap e-commerce styling, distorted products, artificial faces, cluttered backgrounds, an illegible headline, and weak perspective.
