 * SWAG · 統一搜尋元件
 * ───────────────────────────────────────────────────────────────
 * 三頁（指令百科 / 排行 / 主播社群）的搜尋框統一視覺：
 *   - 左側放大鏡 icon
 *   - 右側 ✕ clear 按鈕（有字才出現）
 *   - 統一 placeholder 字級、focus 邊框、shadow
 *
 * 用法：
 *   <div class="swag-search">
 *     <input type="search" class="swag-search-input" placeholder="搜尋指令…">
 *   </div>
 * 也可以用 SwagSearch.upgrade('#你的-input') 自動包裝。
