Focus ring

Single 3px sky ring standard applied to interactive atoms.

Focus rings are a foundation token. Consume the shared token through Concrete primitives instead of restyling focus locally.

Controls update query params directly, so every primitive state can be linked, rendered, and screenshotted deterministically.
