A square 1:1 commercial digital advertising banner and video thumbnail. Subject: One young East Asian man shown from the chest up, seated indoors and leaning slightly forward with his right hand resting thoughtfully near his chin. He has [messy short black hair] and wears a dark navy knit sweater. His face is deliberately anonymized by a vertical rectangular censor blur block centered over his features, dark gray at the top and softly fading lighter toward the bottom. Setting & Background: Defocused futuristic cyber city and digital interface scene with glowing blue gradients, faint bokeh orbs, a sleek curved vertical line, and a subtle double-chevron arrow graphic on the right side. Lighting & Color: Dramatic cool blue side lighting from the right casting deep navy shadows on the left, high-contrast cinematic blue color grading, glossy tech aesthetic. Text & Graphics: Bold white Japanese headline text reading "[バナー]" running across the top edge, cropped so only the lower halves of the characters are visible. Details: Realistic commercial photography, sharp rendering on hair and hand, clean layout, no extra people, no watermarks.
