   0-A. 設計變數（自帶備援，與 aceone_style.css 數值一致）

   背景：本檔案大量使用 var(--primary) / var(--max-w) 等
        在 aceone_style.css 的 :root 中定義的變數。
        若該檔案在首頁未正確載入，這些 var() 會變成「無效值」，
        導致整條 CSS 宣告被忽略（不是退回預設色，而是整條規則失效）：
          .icon-bar{ background:var(--dark) }     → 背景變透明/白色
          .container{ max-width:var(--max-w) }    → max-width 失效，撐滿整頁
          .pc-bg-1{ background:linear-gradient(...var(--primary)...) }
                                                   → 整個 background 失效

        因此這裡重新宣告一份「相同數值」的 :root，
        讓本檔案不依賴外部檔案即可獨立運作。
        即使 aceone_style.css 也正常載入，兩邊數值相同，
        後載入者覆蓋前者也不會造成視覺差異，安全無副作用。

   0-B. Header & Footer（與 aceone_style.css 第3/7節同步備援）

   背景：截圖顯示選單變成無樣式項目清單、搜尋圖示變回平台預設、
        Header 沒有固定/模糊效果、Footer 排版跑掉 —— 這些規則
        定義在 aceone_style.css 的「3. HEADER」與「7. FOOTER」，
        且大多用 !important 覆蓋平台樣式（不只是變數問題）。

        本節將該檔案對應的 Header / 搜尋彈窗(#search) / Footer /
        及其 768px・480px RWD 規則「原樣複製」過來，讓首頁不論
        aceone_style.css 是否成功載入，都能維持一致外觀。

        ⚠️ 注意：內頁專用的聯絡表單 (#contact / .ul_2) 與側邊選單
           (#page_left / #page_main_2) 規則不在此複製範圍內，
           因為首頁不會用到。

        ⚠️ 日後若調整選單／Footer外觀，這裡與
           其他頁面css檔案.css 會有兩份相同規則，建議同步修改，
           避免兩邊樣式日後不一致。

/* ─────────────────────────────────────────────────────
   0-A. 設計變數（自帶備援，與 aceone_style.css 數值一致）

   背景：本檔案大量使用 var(--primary) / var(--max-w) 等
        在 aceone_style.css 的 :root 中定義的變數。
        若該檔案在首頁未正確載入，這些 var() 會變成「無效值」，
        導致整條 CSS 宣告被忽略（不是退回預設色，而是整條規則失效）：
          .icon-bar{ background:var(--dark) }     → 背景變透明/白色
          .container{ max-width:var(--max-w) }    → max-width 失效，撐滿整頁
          .pc-bg-1{ background:linear-gradient(...var(--primary)...) }
                                                   → 整個 background 失效

        因此這裡重新宣告一份「相同數值」的 :root，
        讓本檔案不依賴外部檔案即可獨立運作。
        即使 aceone_style.css 也正常載入，兩邊數值相同，

   0-B. Header & Footer（與 aceone_style.css 第3/7節同步備援）

   背景：截圖顯示選單變成無樣式項目清單、搜尋圖示變回平台預設、
        Header 沒有固定/模糊效果、Footer 排版跑掉 —— 這些規則
        定義在 aceone_style.css 的「3. HEADER」與「7. FOOTER」，
        且大多用 !important 覆蓋平台樣式（不只是變數問題）。

        本節將該檔案對應的 Header / 搜尋彈窗(#search) / Footer /
        及其 768px・480px RWD 規則「原樣複製」過來，讓首頁不論
        aceone_style.css 是否成功載入，都能維持一致外觀。

        ⚠️ 注意：內頁專用的聯絡表單 (#contact / .ul_2) 與側邊選單
           (#page_left / #page_main_2) 規則不在此複製範圍內，
           因為首頁不會用到。

        ⚠️ 日後若調整選單／Footer外觀，這裡與
           其他頁面css檔案.css 會有兩份相同規則，建議同步修改，
           避免兩邊樣式日後不一致。
