   CAIT live demo — hosted/mobile adaptation layer.
   The v2 UI itself is untouched (index.html is the approved
   prototype). This file only adapts the *presentation shell*:
   on phones the app fills the real viewport (no fake bezel /
   status bar); on desktop the device-frame presentation stays.
