Abstract black and white circular vector icon.
A thin circle outline containing several soft, organic curved lines forming a flowing pattern.
The lines should look like stylized topographic curves or raked sand patterns, but simplified and modern.
Balanced composition, with natural asymmetry and strong negative space.
Style: flat vector, solid black lines on white background, no texture, no grain, no shadow, no gradient.
Rounded line endings, smooth curves, minimal, contemporary symbol.
