Retro pixel-art icon on a visibly coarse, consistent logical 32 by 32 square grid, enlarged with hard nearest-neighbor edges. Stair-stepped contours, chunky square pixels, at most four colors including dominant ink, one dark shade, ivory and white. No smoothing, antialiasing, gradients, blur, texture or micro-dithering. Frontal view.

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.
