    Contract

    Semantics first

    Anatomy

    Uses native radio semantics and preserves name/value form submission.

    Consumer classes, styles, and data attributes may extend the surface, but required roles, IDs, relationships, and handlers remain owned by the component.

    Keyboard

    • Tab focuses.
    • Space toggles or selects.

    Version & provenance

    New in the v2 architecture
