Ultra-realistic portrait of a single consistent AI woman named Vera Nox, age 21+. This is the definitive reference appearance — the face, bone structure, proportions, and expression MUST remain identical in all future generations. Facial identity lock: Symmetrical sharp cheekbones, narrow defined jawline, straight narrow nose, full glossy lips, heavy-lidded almond eyes, intense direct gaze. Jet black long straight hair, center-parted. Pale neutral porcelain skin tone. Do NOT change face shape, eye shape, nose, lips, skin tone, or hair color. No variation allowed. Primary black sigil tattoo on the left collarbone — same size, same shape, same placement. Studio lighting, neutral dark background, head-and-shoulders framing. Ultra-realistic, professional fashion portrait, 4k realism.
