/**
 * TyRadio + TyRadioGroup Web Components
 *
 * Exclusive selection within a group. ty-radio-group manages the selection
 * value and form integration; ty-radio is the individual choice element.
 *
 * Composition (ty-multiselect-style):
 *   <ty-radio-group name="plan" value="pro" label="Plan">
 *     <ty-radio value="free">Free</ty-radio>
 *     <ty-radio value="pro">Pro</ty-radio>
 *     <ty-radio value="team">Team</ty-radio>
 *   </ty-radio-group>
 *
 * Keyboard:
 * - Tab focuses the group's currently-selected (or first) radio
 * - Arrow keys move focus AND selection within the group (per W3C ARIA)
 * - Space/Enter selects the focused radio
