Radio Group

Create a Radio Group component for an AI-generated interface using shadcn-style composition. Use shadcn/ui radio-group as the implementation base. The component should support default, muted, error, disabled variants and default, hover, focus-visible, disabled, error, filled states. Include clear anatomy for Root, Item, Indicator, Label, Description. Keep the visual language black, white, and gray with subtle borders, practical spacing, accessible focus states, and no decorative noise.

Do not invent a custom component API when shadcn/ui radio-group already covers the base behavior. Avoid random gradients, oversized radii, unclear disabled states, missing labels, icon-only controls without accessible names, and variants that change layout unexpectedly.

Base: shadcn/ui radio-group
Primitive: Radix Radio Group
Tailwind: Use shadcn tokens for background, border, ring, muted text, radius, and state variants. Keep component-specific classes local and copyable.
Dependency: Use Radix Radio Group through the matching shadcn component when possible.
