/* ========================================================================
   搜索頁面 - 局部樣式表 (Search Page - Local Styles)
   ========================================================================

   專案: 星宇航空物流平台
   頁面: /search
   版本: 1.0.0
   最後更新: 2025-10-05

   設計原則:
   - 僅處理頁面內容區域的局部樣式
   - 不涉及全局佈局 (header, footer, navigation由主模板負責)
   - 採用BEM命名規範 (search-前綴)
   - 響應式設計優先 (Mobile-First)
   - 與首頁/集運頁面保持一致的架構風格

   頁面結構:
   1. 麵包屑導航 (Breadcrumb)
   2. 分類圖標網格 (Category Icons Grid)
   3. 搜索輸入區 (Search Input)
   4. 統計與篩選 (Stats & Filter)
   5. 結果顯示區 (Results Display)
