/**
 * MenuLink Component
 * Navigatielink met niveau-hiërarchie, actieve staat en uitklapbare subnavigatie.
 * Semantisch een `<a>`, visueel consistent met MenuButton.
 *
 * Structuur:
 * <li class="dsn-menu-link">
 *   <a class="dsn-menu-link__link" href="/pagina">
 *     <svg class="dsn-icon" aria-hidden="true"><!-- icoon-start --></svg>
 *     <span class="dsn-menu-link__label">Pagina</span>
 *     <span class="dsn-number-badge dsn-number-badge--negative" aria-hidden="true">5</span>
 *     <svg class="dsn-icon" aria-hidden="true"><!-- icoon-end --></svg>
 *   </a>
 *   <!-- optioneel: scheidingslijn + uitklapknop -->
 *   <span class="dsn-menu-link__divider" aria-hidden="true"></span>
 *   <button type="button" class="dsn-button dsn-button--subtle dsn-button--size-small dsn-button--icon-only dsn-menu-link__expand-button" aria-expanded="false">
 *     <svg class="dsn-icon" aria-hidden="true"><!-- chevron-right --></svg>
 *     <span class="dsn-button__label">
 *       Uitklappen
 *       <span class="dsn-visually-hidden"> voor Pagina</span>
 *     </span>
 *   </button>
 * </li>
 *
 * Niveau-varianten (op het <li>-element):
 *   dsn-menu-link--level-2   (1× level-indent via margin-inline-start)
 *   dsn-menu-link--level-3   (2× level-indent via margin-inline-start)
 *   dsn-menu-link--level-4   (3× level-indent via margin-inline-start)
 *
 * Actieve pagina — border-inline-start indicator op de <a>:
 *   aria-current="page" op het <a>-element → current-kleuren + indicator
 *
 * Uitklapbaar:
 *   aria-expanded="true/false" op dsn-menu-link__expand-button
