/* ==========================================================================
   Demo Mode — loaded ONLY on demo hostnames (see demo_head() in Helpers.php).
   Nothing here can affect the real system: the file is never linked from a
   page served on a non-demo host.

   Two jobs:
   1. Style the always-visible "DEMO MODE" strip (.demo-banner) and the start
      page (.demo-landing).
   2. Make room for that strip. The POS shell is a fixed 100vh kiosk layout
      (no page scroll), the backoffice sidebar/topbar are sticky at top:0 and
      the mobile drawers are position:fixed at top:0, so a strip added above
      them would otherwise push the bottom of each layout off-screen. Every
      such rule is shifted by --demo-h here instead of editing the layouts'
      own stylesheets.
