Ask for the exact thing.

Implement the canonical Radio group component (field.radio-group). Radio group: An input control that gathers, changes, or validates a value. Support these states: default, hover, focus-visible, active, disabled, filled, error, loading. Use semantic design tokens rather than raw visual values. Preserve a minimum 44px touch target where interactive. Provide and verify: implementation, state-matrix, responsive, keyboard, touch, reduced-motion. Keep the component API stable so every Studio kit can supply its own rendering without changing the behavior contract.
