   nav-bubble.css — 漢堡選單問候泡泡套件（2026-07-19）
   老闆裁示：漢堡選單相關功能（問候泡泡/入住退房日/預約紀錄/找回預約）先前
   在 home.html 與共用頁（main.js/style.css）各自維護一份，反覆發生「改了一邊
   忘記改另一邊」的不同步問題。改為套件化：本檔 + /js/nav-bubble.js 是唯一
   事實來源，任何頁面只要載入這兩個檔案即取得完整功能，往後異動只需改這兩個
   檔案，所有頁面自動一併生效。

   完全自成一格（navbk- 前綴），不依賴 host 頁面是否已載入 style.css/
   components.css（home.html 是自包含頁，不載入那兩份）；僅依賴全站共用的
   CSS 自訂屬性（--color-*／--radius／--font-sans，各頁 :root 皆已定義同一組
   設計 token，此為既有穩定契約）。
