/* =============================================================
   Quant Guild — Learning Hub Brand System
   -------------------------------------------------------------
   Brings the Quant Courses / subscribe brand-panel design language
   (deep QG-blue gradient hero with grid texture, floating glass
   panels, gold accents) to the desktop Dashboard, History,
   Bookmarks, and Roadmap pages.

   Scoped under .learning-hub-page and targeted at the desktop
   .main-content so the bespoke mobile layouts are untouched. It
   deliberately restyles existing wrappers (.dashboard-header,
   .section-box, .stats-grid, tables) WITHOUT renaming the
   selectors/ids the page JS depends on.
