/* ===========================================================================
   JACRA Backoffice - command palette (Ctrl+K)
   ---------------------------------------------------------------------------
   Built by assets/js/commandbar.js and appended to <body>, so it sits outside
   the app shell and above every screen.

   Load AFTER components.css and mobile.css, with the other screen sheets:
     <link rel="stylesheet" href="assets/css/screens/commandbar.css">

   Two forms, one stylesheet:
     - desktop: a 640px card that drops in from just above the fold
     - phone:   a full sheet from the top edge, so the on screen keyboard has
                the whole viewport to work with and no card floats behind it

   Layer order in this app: bottombar 50, toast 60, palette 90. The palette
   covers the tab bar because it is modal; the floating launcher underneath it
   sits at 45, below the bar it must never hide.

   Colour comes from tokens.css only. The scrim is --navy-900 carried at
   partial opacity on its own element rather than a hand mixed rgba(), which is
   also what lets the blur and the wash fade in together.
