/* =============================================================
   VIDEO LEARNING PAGE STYLES  (/{lang}/video-learning)
   Views/VideoLearning/Index.cshtml

   Extracted from VedicSagePublic.css so this page renders correctly
   under BOTH presentation modes:

       anonymous  -> _LayoutUnauthorized.cshtml
       logged in  -> LayoutHelper.GetLayout() (role/session layout)

   The page loads this file itself through @section Styles, which both
   layouts render, so VedicSagePublic.css is NOT pulled into
   authenticated pages.

   Every selector below is .vs-vl-* scoped: no body/html/:root rules and
   no dependency on public header, footer or Home CTA styles.

   .vs-vl-scope redeclares the nine VedicSage tokens the block consumes
   so the page is self-sufficient under either layout. The tokens are
   intentionally NOT moved to :root, which would leak into authenticated
   pages and alter VedicSageTheme.

   AUTHENTICATED LAYOUT MODIFIER

   Applied only when the visitor is signed in, via the .vs-vl-authenticated
   class the view adds to its scope wrapper.

   The public layout gives .vs-vl-hero a tall full-bleed band. Inside
   _LayoutInsp4Horizontal.cshtml the page already sits below the breadcrumb
   inside .content-page, so that offset becomes dead space. This trims it so
   the hero starts naturally under the breadcrumb. Nothing else is changed:
   no markup is duplicated and the anonymous branch is untouched.
