Photoreal librarian presenting AI book

A realistic, vertical promotional portrait is set against a warm, modern library or bookstore interior. A young East Asian woman stands behind a wooden counter, displaying a large book to the camera. She has long, straight, dark brown hair parted in the middle, wears delicate earrings, and appears neat, friendly, and professional. She wears a white shirt, a soft green striped tie, and a beige apron with a name tag reading "Librarian Ai-chan" and a small open book icon sewn on it. Her left hand holds the book upright against her chest, slightly tilted towards the viewer, while her right hand is open beneath the book, a classic product presentation pose. The book is the visual focus: its dark, glossy cover features a striking orange title, "Pollo AI" (a large line of text at the top, with a glowing line in the center), followed by a smaller Japanese subtitle and functional description, and a circular "P" logo in the lower left corner. To the left of the counter is a transparent acrylic nameplate with Japanese text above and the prominent "Ai-chan" logo below. To the right of the counter, three hardcover books are stacked horizontally, each with a numbered label and a Japanese title on its spine. Against a softly blurred background, a tall wooden bookshelf stands on the left, displaying books, small potted plants, and a warm-toned lamp; a decorative painting with Japanese text hangs on the upper right wall; and a potted green plant sits on the far right. A small white "Pollo.ai" watermark is added to the upper right corner. The image uses warm ambient lighting, a shallow depth of field, and primarily beige and wood tones to depict realistic skin and fabric textures. The composition is simple, giving it the feel of a professional lifestyle advertisement. The composition is a portrait from mid-thigh to head, in a 3:4 ratio.
