/* =====================================================
   Portal Shell — Shared Layout System
   Version: 1.0

   SCOPING: All styles are under .portal-page or .portal-*
   classes. Legacy pages that don't use these classes are
   completely unaffected. Onboarding (.ob-*) and Dashboard
   (.dash-*) have their own namespaces and are not touched.

   USAGE: Wrap your page in <div class="portal-page"> and
   use .portal-content, .portal-card, .portal-subtabs etc.
   See Shell Usage Guide for details.
