/* WrapServicer v2 — shared portal chrome
 * Mobile-first shell layout layered on top of tailwind.css / brand.css.
 * No @tailwind directives here — this file extends, never duplicates.

 * Token sources:
 *   var(--ws-*)            brand.css custom properties
 *   env(safe-area-inset-*) device safe-area (iOS notch / home indicator)
 *
 * BEM structure:
 *   .app-shell              Root shell viewport wrapper
 *   .app-shell__sidebar     Off-canvas on mobile, fixed rail on desktop
 *   .app-shell__frame       Right column (topbar + scrollable main)
 *   .app-shell__topbar      Sticky header strip
 *   .app-shell__main        Scrollable content area below the topbar
