/* ============================================================
   THINKBENCH PORTAL — Core Lite private pilot
   App chrome. Calm, premium, trustworthy. Blue → teal brand.
   Source: Claude Design project "Thinkbench Portal" (portal.css),
   adapted as static CSS for the server-rendered Blazor UI — no JS
   framework dependency, same visual language.

   Brand/status tokens and the CSS backing the shared
   Thinkbench.DesignSystem components (ThCard, ThPageHead, ThPill,
   ThStat, ThKpiGrid, ThAlertBanner — .pill/.stat/.kpi-grid/.page-head/
   .soft and the :root token block) now live in that RCL's own
   design-system.css, loaded via App.razor before this file. Everything
   below is Portal-specific chrome only — its own .card look, sidebar,
   buttons, tiles, etc. — see docs/design-system/REVIEW-2026-06-22.md §4.
