/* ============================================================
   CaRD Connector für SharePoint — EDITORIAL THEME (alternative)
   Warm off-white canvas, a dramatic dark navy hero & CTA as
   "bookends", left-aligned section heads, crisp bordered cards,
   indigo accent. Same class names as the other themes so the
   HTML stays identical.
