Simple Black Circle Outline Design

A crisp, pixelated outline of a circle stands out against a deep black background. The design is simple and features two distinct grey lines that form the perfect circular shape, giving it a subtle, double-edged appearance. It's a minimalist piece that suggests a digital aesthetic, perhaps suitable for an icon, a game element, or a placeholder in a dark mode setting.
