/**
 * Smart Ajax Search - Frontend Styles
 *
 * STRATEGY: CSS isolation
 * - Reset toàn bộ thuộc tính kế thừa từ theme với `all: revert` ở wrapper
 * - Set !important cho các thuộc tính LAYOUT-CRITICAL (display, width, height,
 *   padding, margin, position, flex) để theme không ghi đè
 * - Không dùng !important cho màu sắc / radius để vẫn cho phép custom qua CSS variables
