#  DigitalWall - Raspberry Pi kiosk
#  Turns a Raspberry Pi into a dedicated DigitalWall screen: boots straight into
#  the player, full-screen, with the display kept awake.
#
#  Quick start (Raspberry Pi OS with desktop):
#    chmod +x digitalwall-rpi-kiosk.sh
#    ./digitalwall-rpi-kiosk.sh
#
#  Auto-start on boot — create ~/.config/autostart/digitalwall.desktop with:
#    [Desktop Entry]
#    Type=Application
#    Name=DigitalWall
#    Exec=/home/pi/digitalwall-rpi-kiosk.sh
#    X-GNOME-Autostart-enabled=true
#
#  On first run, pair the screen with the 6-character code it displays.
