/* =========================================================
   BS5 v5 page-specific minimal patch
   Target: A-NAV top-level parent menu caret display only
   Reason: Bootstrap 5 .dropdown-toggle::after adds a ▼ to every top-level
           dropdown item. The requested desktop state is:
           - Remove ▼ from: 公司訊息 / 產品應用 / 產品資訊 / 專業服務 / 聯絡我們
           - Keep single ▼ on: 繁體中文, using the existing legacy span.caret
   Frozen: Bootstrap 5.3.8 local assets / shared CSS & JS / desktop navbar
           nowrap / transparent-to-black scroll state / third-level submenu
           expansion / footer / homepage content DOM.
