/**
 * Indicator thumb style definition
 *
 * @note ANIMATED PROPERTIES (cannot be set via className):
 * The following property is animated and cannot be overridden using Tailwind classes:
 * - `transform` (specifically `scale`) - Animated for selection transitions (unselected: 1.5, selected: 1)
 *
 * To customize this property, use the `animation` prop on `Radio.IndicatorThumb`:
 * ```tsx
 * <Radio.IndicatorThumb
 *   animation={{
 *     scale: { value: [1.5, 1], timingConfig: { duration: 300, easing: Easing.out(Easing.ease) } }
 *   }}
 * />
 * ```
 *
 * To completely disable animated styles and apply your own via className or style prop,
 * set `isAnimatedStyleActive={false}` on `Radio.IndicatorThumb`.
