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 Korean woman in her early 60s, silver hair in a tight short crop, small sensor dots along one temple. Pale laboratory overlayer with a living green-tinted algae culture panel sewn flat into the chest like a breathing patch. Synthetic-biology aquaculture technician. Photorealistic portrait
