# install.sh - Modular management entry point for Ubuntu Based Kiosk.
#
# This is NOT yet the full system installer - that is still the big
# single-file script (ubuntu-based-kiosk-v1.0.3.sh etc) documented in
# Readme.md, and first-time provisioning of a new kiosk still goes through
# it. This entry point is the start of pulling the *menu system* out of
# that 12k-line file into small, independently editable modules under
# lib/ and menus/, so a change to (say) the Sites menu can't accidentally
# break WiFi setup or the uninstaller three thousand lines away.
#
# Today this wires up Sites & Page Timing (menus/sites.sh) and Display &
# Interaction (menus/display.sh). The rest of Core Settings/Addons/Advanced
# will move over the same way, one menus/*.sh file at a time.
#
# Usage (once the kiosk has already been installed):
#   git clone <repo>
#   cd ubuntu-based-kiosk
#   ./install.sh
