   -----------------------------------------------------------------------------
   獨立頁面（原 marketing-content.php 的電子展板頁籤），只收錄
   includes/cases-data.php 的 display 分類。案例縮圖統一套上深色看板邊框，
   呼應觸控電子看板的產品情境。進場動效沿用 css/aais-home.css 的
   [data-reveal] 機制（IntersectionObserver＋fail-open）。
   色彩、字體、字級、圓角、陰影一律來自 design-system/tokens.css 與
   design-system/components.css，不在此重複定義。
