Image-to-Image / Sketch Render Prompt (线稿上色/草图渲染)

Render the attached sketch into a finished {{style: Pixar-like 3D animation still / watercolor illustration / realistic product design}} while strictly preserving the original composition, camera angle, proportions, and object placement. Add: materials {{brushed steel, frosted glass, oak}}, lighting {{soft studio key + blue rim}}, background {{neutral gradient studio}}, ambient occlusion in crevices, coherent palette {{#list}}. Nothing should be added or removed in silhouette; keep line-art structural edges readable. (Workflow: SD img2img denoise 0.35-0.55 low for fidelity / ControlNet canny+depth on; higher 0.6 for stylization.)
