Futuristic AI Sports Poster

A cinematic vertical poster of {argument name="subject name" default="tech founder"} styled like a futuristic football superstar campaign image, waist-up portrait, centered, arms crossed, wearing a plain dark navy or black crewneck sweater, confident and calm posture, looking slightly off-camera. Place him inside a dramatic high-tech stadium or arena at night with bright floodlights glowing from the upper left, dark steel architecture overhead, and a cool blue sci-fi atmosphere. Add floating particles and light debris in the air for energy and motion. Surround the subject with futuristic AI interface graphics: 1 glowing wireframe cube icon on the left side, 1 luminous digital brain or neural-network globe on the right side, and multiple transparent holographic dashboard screens with charts and data panels behind him. Use a deep blue, black, and white color palette with sharp contrast, glossy highlights, subtle lens glow, and premium blockbuster poster lighting. Make the composition sleek, aspirational, and tech-forward, like a sports ad merged with artificial intelligence branding. At the bottom, add the title text {argument name="main title" default="THE FUTURE"} in very large metallic white uppercase letters, with the word "THE" smaller above the main word, and add the tagline {argument name="tagline" default="Built with Intelligence"} below in smaller spaced-out sans-serif text. Include faint hexagonal HUD linework near the lower corners and a glowing horizontal light streak cutting through the title area. Ultra-detailed, photorealistic, poster design, polished commercial key art, 9:16 aspect ratio.
