SecuBox Mode Switcher

Usage: secubox-mode <command>

Commands:
  kiosk     Switch to Kiosk mode (GUI with Chromium)
  tui       Switch to TUI mode (Console dashboard)
  console   Drop to console (disable both modes)
  status    Show current mode

The mode switch takes effect on next boot, or immediately with --now flag.

Examples:
  secubox-mode kiosk     # Enable kiosk mode
  secubox-mode tui --now # Switch to TUI immediately
  secubox-mode console   # Disable both, drop to login shell
