 * Choice Group Header - A semantic heading element for grouping related choice items.
 *
 * @description
 * The Choice Group Header component provides a labeled section header for organizing
 * groups of radio buttons, checkboxes, or other choice elements. It automatically assigns
 * to the 'header' slot and includes appropriate ARIA role='heading' for accessibility.
 * This component helps create clear visual and semantic groupings within forms and
 * choice-based interfaces, improving usability and screen reader navigation. It is
 * typically used within Choice Group containers to separate related options.
 *
 * @name Choice Group Header
 * @element mosaik-choice-group-header
