/* ==========================================================================
   SIBERIA CLUB - SITE THEME (shared shell)
   Ported from template-8-sibir-club. Used by Views/Shared/_SiteLayout.cshtml on
   every themed page: variables, base type, top bar, dropdowns, footer.
   Home-only sections live in home.css; the skin for the older Bootstrap page
   content (events, points, login, ...) lives in inner.css.
