# 09-Setup-Display.ps1 -- Display pc-type setup (runs after Shopfloor baseline)
#
# Display = lobby display / dashboard kiosk PC. Kiosk app itself
# (LobbyDisplay or Dashboard) installs via preinstall.json (Install-
# KioskApp.cmd reads display-type.txt). No OpenText, no eDNC, no UDC.
#
# This script applies Edge kiosk-mode relaunch policies so the
# "An update is available - restart Edge" dialog auto-clears without
# requiring keyboard/mouse interaction (display bays have neither).

# --- Arm the ShopDB kiosk bootstrap -------------------------------------

# until the bay joins the AESFMA wifi SSID. So it cannot run now.

# Register a SYSTEM task that does nothing until ShopDB answers, then runs the
# vendor installer once and unregisters itself. At boot and every 15 minutes,
# so a bay cabled up days later still self-configures.
