年轻日本女性的写实咖啡馆肖像

Create a realistic smartphone-style candid photo of a {argument name="subject" default="young Japanese woman"} seated indoors at a cafe, photographed by someone else rather than as a selfie. She is centered in a vertical portrait composition, shown from about mid-torso upward, facing the camera with a gentle smile. She has {argument name="hair color and style" default="dark brown, shoulder-length softly wavy hair with a natural center part"} and wears a {argument name="outfit" default="cream white ribbed knit cardigan with small front buttons"}, with a delicate small necklace barely visible at the collar. Use natural daylight from a large window on the right side, soft realistic skin tones, casual phone-camera perspective, and slight background depth. The cafe background includes a wooden counter on the left rear, warm pendant lighting, a pastry/display case, bottles and small decor on the counter, a chalkboard menu with handwritten seasonal items, black chairs and tables, gray tile flooring, and a large black-framed window on the right showing green plants outside. The mood should be everyday, authentic, and unpolished, like a real photo taken in a modern Japanese cafe. Keep the subject looking directly toward the lens; do not make it a selfie, studio portrait, fashion shoot, or heavily edited image. Use portrait orientation, realistic lighting, natural colors, and smartphone photo quality.
