/* ============================================================
   trust-portal.css — Vakio Trust Portal v1 (TRUST-1)
   Covers all .trust-* classes used by:
     frontend/assets/js/pages/TrustPosturePage.js
     frontend/assets/js/components/TrustPostureBanner.js

   Design discipline:
     - All colour/spacing/radius via design-system.css tokens — no hardcoded
       values for grade colours.  Each grade pill carries both an icon AND a
       textual label so colour is never the only signal (WCAG SC 1.4.1).
     - Logical CSS properties used so the banner is RTL-ready when an RTL
       locale lands (margin-inline-start, padding-inline, etc.).
     - prefers-reduced-motion honoured by reusing animate-fade-in from
       main.css (no new animations introduced here).
