Use case: precise-object-edit. Input is hasui-08a, an original contemporary illustration inspired by Kawase Hasui. Correct ONLY the indoor floor. The scholar's studio floor must read as dry, matte aged wooden boards with a subtle warm brown wood grain and soft diffuse shadows. Remove all puddle-like bright fragmented reflections, wet streaks and watery shine under the table, scholar and chair. Keep the outdoor rain, mountain mist and river completely unchanged. Preserve exactly the man's face, apparent age, gaze, pose, both hands, brush, painting, table, chair, bamboo, all other objects and their placement, robe and detailed border, color woodblock style, framing and 1024x1536 portrait proportions. The dry floor should share the existing soft daylight, and all furniture feet and shoes must remain grounded. No new props, no signatures, text or border. Opaque full scene.
