Art style: шерли.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Shirley, a sleek anthropomorphic black cat detective with glossy jet-black fur, an elegant slender feline build, upright bipedal posture, and a long expressive tail curling behind her. Her most striking feature is her piercing golden eyes, sharp and clever, set in a fine-boned feline face with alert pointed ears and delicate whiskers. She wears a brown checkered deerstalker cap tilted with confidence, a matching brown plaid detective coat cinched at the waist, and a small cream cravat at her throat. One paw holds a brass-rimmed magnifying glass raised near her chin. She stands on tidy black-furred hind paws. A cocked-brow, knowing, slightly ironic smirk. Setting: a cozy dim detective study with bookshelves, a small wooden desk, and a warm lamp.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "шерли" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "шерли". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "шерли" idiom, not in any other medium.
