Anonymous Blue Tech Thumbnail

Create a square 1:1 digital advertising banner or video thumbnail featuring one young East Asian man seated indoors in a futuristic blue tech environment. The man has {argument name="hair style" default="messy short black hair"}, wears a dark navy knit sweater, and is shown from the chest up, leaning slightly forward with his right hand resting near his chin in a thoughtful pose. His face is deliberately anonymized by one large vertical rectangular blur/censor block centered over the face, dark gray at the top and fading slightly lighter toward the bottom. Use dramatic cool blue lighting from the right, with a deep navy shadow on the left side of the subject. The background is an out-of-focus cyber city or digital interface scene with glowing blue gradients, faint bokeh lights, one curved vertical line on the right, and one subtle double-chevron arrow symbol on the right side. Add large bold white Japanese-style headline text across the very top, cropped so only the lower parts of the characters are visible, suggesting a thumbnail title; use {argument name="headline text" default="バナー"} if full text is needed but keep it partially cut off by the top edge. Composition: one person, one face-obscuring rectangle, one cropped headline area, one right-side chevron graphic. High-contrast glossy commercial look, realistic photo-based rendering, sharp subject hair and hand details, cinematic blue color grading, no watermark, no extra people, no extra readable text.
