/**
 * A `Radio` component for rendering a group of radio buttons.
 *
 * This component supports selecting a single value from a list of options.
 * It gracefully handles edge cases such as empty options, duplicate values,
 * and ensures predictable behavior by automatically selecting the first
 * occurrence of a duplicate value.
 *
 * @component
 *
 * @param {RadioInputType} props - The props for the Radio component.
 * @param {string} props.name - The name of the radio input group.
 * @param {string} props.label - The label displayed above the radio group.
 * @param {string | number} props.value - The currently selected value of the radio group.
 * @param {(value: string | number) => void} props.onChange - Callback invoked when a radio button is selected.
 * @param {{ label: string, value: string | number}[]} props.options - Array of options for the radio group. Each option contains:
 * - `label`: The display text for the radio button.
 * - `value`: The value associated with the radio button.
 *
 * @example
 * const options = [
 *   { label: 'Option 1', value: 'option1' },
 *   { label: 'Option 2', value: 'option2' },
 *   { label: 'Option 3', value: 'option3' },
 * ];
 *
 * <Radio
 *   name="example"
 *   label="Choose an Option"
 *   value="option1"
 *   onChange={(value) => console.log(value)}
 *   options={options}
 * />
 *
 * @returns {JSX.Element | null} The rendered radio button group, or null if no options are provided.
