/* ============================================================
   Shipping Tabs — 運費試算 tab/pane 樣式 + 直播大字版 badge
   結構/樣式/行為分離（2026-06-27）：原 _shipping-tabs.blade.php 的
   inline <style>（L2-30）逐行抽出；外部連結 badge 的 inline style 與
   onmouseover/onmouseout → class + CSS :hover；外觀完全一致。
   試算數學邏輯仍在 import-cost-addon.js / tw-delivery-calc.js。
