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 30s, close-cropped hair, faint salt-crystal residue along her jawline. Teal dive-support layer with translucent gill-like vents at the shoulders and a slim biometric collar glowing faintly cyan. Artificial coral reef cultivator. Photorealistic portrait
