/* =============================================================================
   Connect Shell — Wave 3 DEV-1 (additive, frontend-only)
   3-pane, dual-mode, offset-aware messaging shell for messaging-hub.html.

   - Height = calc(100vh - var(--app-header-offset)) (NOT h-screen) so it sits
     flush below the shared header in standalone mode and flush to the top of
     the dashboard iframe when embedded (--app-header-offset = 0).
   - Gold brand tokens (var(--marriage-gold) / var(--love-pink)); text/icons on
     light surfaces use --marriage-gold-700 via a11y.css .gold-text/.gold-icon.
   - Drawers (Column C / image / video / family) are offset-aware: position:static
     or display:none under html.page-mode-embedded so they NEVER float over the
     dashboard chrome. Re-keyed away from `fixed inset-0 z-50`.
