  "prompt": "A realistic front-facing smartphone selfie of the same woman (use uploaded photo as exact face reference, preserve every facial feature, skin detail and expression without alteration or beautification) taken inside a modern car during daytime. Framed from upper chest to top of head, she's sitting in the driver's seat, holding a dark gray iPhone (visible triple-camera module) in her right hand extended at classic selfie distance (~arm's length), looking directly into the phone screen with a relaxed, subtle closed-mouth smile and natural eye contact. Slight 5-10° head tilt to her left for candid feel. Shot simulation: smartphone front camera ~24-28mm equivalent, natural wide-angle perspective with very mild edge distortion typical of phone selfies, eye-level framing. Bright natural daylight streaming through windshield and side windows (mid-morning to early afternoon, clear weather), creating soft even illumination on face with gentle highlights on cheekbones/nose/forehead, subtle catchlights in eyes, realistic soft shadows under chin and from dashboard below. Preserve authentic skin: visible pores, natural texture, light imperfections, subtle oil sheen if present, no smoothing or filters. Medium-length dark brown hair with soft loose waves, slightly tousled from driving, a few strands across forehead. Wearing casual everyday outfit: fitted white cotton t-shirt or simple crew-neck tee, light denim jacket or open cardigan, small gold necklace and stud earrings. Delicate fine-line tattoo visible on inner right forearm if in reference. Background: clean modern car interior — black or gray leather seats, visible steering wheel on left, dashboard with subtle reflections, side window showing blurred outdoor street/parking lot scene (trees, buildings or road softly out of focus with natural bokeh), everything believable and non-distracting. Ultra-sharp focus on face and phone hand, photorealistic color grading with natural contrast, high dynamic range, candid everyday smartphone selfie aesthetic, authentic lens character, no artificial glow, no over-sharpening, no beauty edits.",
