/* ============================================================================
   Varuna Portal Theme (standalone)
   Every rule is scoped under .portal-shell so nothing leaks into the public
   homepage (Classic or SiteBuilder mode) or other layouts. Plain CSS by
   design: this project has no CI sass step (main.css is a committed Web
   Compiler artifact), so hand-written CSS is the only pipeline-safe option.
   The per-tenant accent is injected by PortalLayout as --portal-accent.
