Photorealistic Amber-Eyed Cat Portrait

Create a highly realistic studio portrait of a long-haired [cat breed] facing forward, centered in a tight head-and-chest composition. The cat has dense fluffy fur in [fur colors], with a white muzzle, white chest ruff, a narrow white blaze running up the nose and forehead, darker gray tabby shading over the crown and cheeks, and long fine whiskers spreading horizontally. Show exactly two large upright triangular ears with pale pink inner skin and wispy ear tufts, exactly two vivid [eye color] almond-shaped eyes with vertical slit pupils, and a small soft pink nose. The expression is calm, intelligent, slightly serious, with symmetrical frontal eye contact. Use photorealistic detail: individual fur strands, soft natural texture, subtle depth of field, and crisp focus on the eyes and face. Background is a plain smooth [background color] studio backdrop, softly blurred, with no props, no text, no collar, no watermark. Lighting is gentle diffused studio lighting from the front-left, creating soft highlights on the fur and natural shadows under the chin. Vertical square-ish portrait framing, close crop with the ears near the top edge and the fluffy chest filling the lower frame.
