/* =====================================================================
   Pantexis LMS + Blocking Gate stylesheet.

   Conventions:
   - Reuses existing wt-* tokens from Pantexis.Rcl/wwwroot/css/app.css
     where possible (colors, typography), but namespaces LMS-specific
     layout under .lms-*. The blocking-gate UI is namespaced .wt-blocking-*
     because it lives in the topbar shell alongside the rest of wt-*.
   - All layout uses CSS grid / flex with sensible breakpoints down to
     360px so the orchestrator and player work on phones.
   - Color hex values intentionally avoid theming variables so this
     drops in standalone; promote them to CSS custom properties when
     branding tokens are extracted.
