/* ============================================================================
   Phase 6 Step 2 — App shell (FlyWP IA): top app-bar + More menu + avatar menu
   + mobile bottom-nav + resource-scoped sidebar.
   ADDITIVE & ISOLATED: nothing here applies until dashboard.html opts in by
   rendering .appbar / .bottomnav. Old .sb/.topbar styles remain untouched in
   layout.css until the swap is verified. All colors via base.css tokens.
