 * TinyHtmlRadioInput is a helper class for managing `<input type="radio">` elements.

 *
 * @example
 * const radio = new TinyHtmlRadioInput({
 *   name: 'gender',
 *   value: 'female',
 *   checked: true,
 *   required: true
 * });
 *
 * // Check state
 * radio.checked = false;
 * console.log(radio.checked); // false
