/* ===== Shell — Concierge two-column grid =====
   layouts/base.html mounts .app whenever the viewer has a User and
   the page is NOT NoChrome (auth / take / security / privacy /
   report pages render document-first into <main class="page"> only).
   The sidebar partial (partials/sidebar.html) branches on .Scope and
   carries the workspace identity card + hierarchical sub-nav + member
   footer. The topbar carries breadcrumbs + the org-switcher popover.

   Two body classes carry orthogonal context:
     - body.platform        — viewer holds a platform role (used by
                              .btn--primary below; pre-PR semantic).
     - body.scope-platform  — current PAGE is in /platform scope (used
                              by sidebar / sb-mark / eyebrow tinting).
   Don't gate scope-driven shell tinting on body.platform — a platform
   admin viewing an /app/ page would mis-tint the app sidebar + eyebrows. */
