Uniform medium-thin strokes, rounded caps and joins, generous negative space. Frontal geometric contours with white interiors. Keep only essential internal details at equal stroke weight. No fills, shading, gradients, texture or perspective.

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.
