Inpainting / Editing Instruction Prompt (局部重绘)

Task: edit ONLY the masked region; preserve everything else pixel-consistent (lighting direction, color temperature, perspective, grain, focus level). Masked area currently contains: {{what is there now}}. Replace with: {{exact object/feature, material, color, pose}}. Match: same key-light direction from {{upper-left}}, same shadow softness, same lens blur depth, same image resolution and noise/grain; the edit boundary must be invisible; cast a physically correct contact shadow if the new object rests on a surface. Do not alter background, face, or unmasked clothing. (SD inpaint settings: denoise 0.6-0.85, masked content "original", padding 32.)
