   lgw-browse-by-dmd-heading.css
   CSS cho webpart Library/Webparts/BrowseByDmdHeading + Library/Webparts/MenuHeading
   (khi dùng trong trang BrowseByDmdHeading.aspx).

   Toàn bộ class ở đây dùng tiền tố "bdh-" (BrowseByDmdHeading) để không đụng
   tới class "kps-*" gốc (kps-collection-tree / kps-browse-card, dùng bởi
   CatalogCollections / BrowseByCollection) — tránh 2 tính năng vô tình ảnh
   hưởng chéo lẫn nhau khi 1 trong 2 bên cần chỉnh riêng sau này.

   Cấu trúc HTML mượn lại nguyên bản từ:
   - .bdh-collection-tree: giống CatalogCollections.ascx (asp:TreeView) ->
     Library/Webparts/MenuHeading.ascx đã viết lại dùng asp:TreeView.
   - .bdh-browse-card: giống Files/Templates/vi/kpsdsp_bib_card.xsl ->
     Files/Templates/vi/kpsdsp_thumbtitlesummaryleft.xsl / right.xsl.

   Biến màu (--hanu-*, --archive-brown-dark, --orange-6/700) dùng lại từ
   :root khai báo trong lgw-hanu.css (nạp trước file này trong Bundle.config).
