Orthographic isometric view, parallel receding edges around 30 degrees, no vanishing point. Crisp planes and shallow visible thickness. Use three flat light-to-dark planes within each assigned part color, with ivory secondary surfaces when needed. No outlines, gradients, photoreal textures, soft clay forms or cast shadow.

Square canvas, at least 1024 × 1024. Center one complete subject with 15% empty margin; readable at 96px. Pure opaque white background. No text, numbers, logos, watermark, frame, loose decorations or extra objects. Deliver one icon, not a sheet. If an example image is attached, use only its style; replace its subject with the requested subject.
