/*
 * Tab navigation — pill/segmented control style.
 * Works with <button> elements (Stimulus client-side) and <a> elements (server-side link_to).
 *
 * Usage:
 *   <div class="tab-nav" role="tablist">
 *     <a class="tab-btn tab-btn--active" href="?filter=live">Live</a>
 *     <a class="tab-btn" href="?filter=settling">Settling</a>
 *   </div>
 *
 * Or with Stimulus:
 *   <div class="tab-nav" data-controller="games-tabs" role="tablist">
 *     <button class="tab-btn tab-btn--active" data-tab="all" data-action="...">All</button>
 *   </div>
