/* ==========================================================================
   App top bar — the "context bar" (6 Oct 2026)
   --------------------------------------------------------------------------
   Left:   menu · business switcher (logo, name, and a line with the branch
           and plan: App._updateTopbarContext in shell-nav.js)
   Middle: a search box on wide screens (Ctrl/Cmd + K opens it too), an icon
           on phones
   Right:  "+ New" · flag and bell in one soft group · you (photo, name, role)

   Scoped to #main-app's top bar and linked after every other sheet, so the
   older .topbar rules in app.css are overridden here rather than edited.
   True-black primary text; greys no lighter than #475569.
