鮮やかなグラデーション、静かな自信

16:9 horizontal banner / YouTube thumbnail, a photorealistic editorial-style portrait as the main focal point. A stylish young woman in her late 20s, slender build, East Asian features, with confident calm expression, looking slightly away from camera, standing in a clean open space. She wears a crisp white blouse and light beige wide-leg trousers, no logos. The background is a duotone mesh gradient (magenta × cyan) covering the entire frame like a modern graphic texture, but soft and clean, not harsh. Lighting is bright natural daylight with soft shadows, creating a premium editorial look. At the top of the image, large bold white Japanese text “デュオトーンのメッシュ” with slight drop shadow. Across the middle, a horizontal semi-transparent white band containing the main headline “マゼンタ×シアン” in large bold black type. At the bottom right, small text “水平のコピー帯”. Layout: person positioned slightly off-center left, text layer runs across the middle. Overall tone is bright, airy, pastel-infused, with generous negative space. No logos, no watermarks, no English decorative text. The person must be rendered as a photorealistic photo, not illustration or 3D.
