/* ==========================================================================
   貓貓谷 註冊彈窗精修 2026-11-06（v5：質感版，修正電腦版導覽列遮擋與矮螢幕）
   以 10/17–10/25 的米金色舊款為底，原廠美術只用在最有分量的地方：
   - 頂部主視覺：遊戲登入畫面插畫（UI/LoginBack.img/Title/0）
   - 標題徽記、註冊成功：升級特效的金色楓葉（Effect/BasicEff.img/LevelUp/9）
   其餘以排版、細金線、留白與柔和陰影收斂，不堆小圖示。
   只覆蓋 #register-modal 的外觀。不改 HTML、表單、按鈕文字、JS 與任何事件。
   手機的高度、捲動、鍵盤與安全區由 registration-mobile-scroll（11/06）負責，這裡不覆蓋。
   還原：刪掉引用這個檔案的那一行 <link>。
