A passport-style ID photograph of a person. The photograph itself fills the entire frame edge to edge — not a document, not a card, no text, no borders. STRICT FRAMING: crop ends at the middle of the upper arm, nothing below the armpit in frame. Straight on at exact eye level, centred, looking into the lens, calm neutral expression. BACKGROUND: completely FLAT uniform pale mint-green, one even tone, NO gradient, NO shadow. Flat frontal lighting. The subject: a young man in his 20s of mixed Korean and West African descent, short twists, a slim transparent earpiece behind one ear. Light grey climate-control shell with a temperature-gradient stripe across the chest shifting from blue to amber. Urban microclimate engineer. Photorealistic portrait
