Librarian in Neon Casino: Photorealistic Scene

Hyperrealistic, photorealistic image of a calm librarian in a luxurious casino. A female librarian with a neat bun and round glasses, wearing a tailored charcoal blazer, crisp white blouse, and black pencil skirt. She stands near a marble information desk, holding an open leather-bound book in one hand and a few index cards in the other. Behind her, a casino floor glitters with neon signs, a blurred roulette wheel, and slot machines. Warm tungsten lighting contrasts with cool blue neon reflections on polished floors. 3/4 portrait, shallow depth of field, high detail on fabrics, leather, and paper textures, cinematic composition, 8K realism, mood of quiet authority amid casino bustle.
