/* ===== Mega menu：desktop 側欄+內容雙欄／mobile 手風琴，共用同一份 markup =====
   結構：.mega-menu-list > .mega-item > .mega-tab + .mega-panel
   Mobile（預設）：一般文檔流，click 一個 tab 就喺佢下面展開自己嗰個 panel（手風琴）。
   Desktop（lg 或以上）：.mega-tab 保持正常文檔流（喺左欄疊埋，唔會因為右邊內容高度被谷高）；
   .mega-panel 用 position:absolute 疊喺右邊內容區，靠 .active 決定顯示邊個。
   容器高度由 JS（applyMegaPanelHeight，喺 header 嘅 inline script 入面）跟住現時顯示緊嗰個
   panel 嘅實際內容高度同步更新，避免唔同分頁內容高度唔一嘅時候溢出或留白。 */
