/* ==========================================================================
   Page frame: tower + pane.

   The app layout (`app.rs` → AppShell) renders the storefront tower and a
   pane (navbar · routed page · footer) on every public route:

     phones / tablet portrait      desktop / tablet landscape
     ─────────────────────────     ───────────────────────────────
     `/`   : tower only            tower (sticky, viewport-tall)
     other : pane only             | pane (scrolls)

   Everything below the breakpoint keeps the original behaviour; the split
   is added on top. Loaded after restaurant.css so its overrides win.
