   訂單秘書 — 產業頁共用樣式（/trades/*/index.html）

   這一份是從 index.html 的內嵌 <style> 挑出「產業頁真的會用到」的部分，
   加上幾個產業頁專屬的元件（麵包屑、一天的時間軸、對照表、其他產業導覽）。

   為什麼產業頁用外部 CSS、首頁還是內嵌？
     · 首頁只有一頁，內嵌少一次請求，首屏最快；
     · 產業頁有六頁、樣式完全一樣，共用一份檔案第二頁之後直接吃快取，
       而且要調樣式時只改這裡一個地方，不用改六次。

   色票、字體、動效 token 與 index.html 完全一致——改主視覺時兩邊要一起改。
