# 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.sh) documented in Readme.md, and
# first-time provisioning of a new kiosk still goes through it. That file
# still also contains its own (unmigrated, unmodified) copies of every
# menu below - both copies coexist deliberately until enough of Core
# Settings/Addons/Advanced has moved over to retire the old ones in one
# pass. This entry point is the modular replacement, one menus/*.sh file
# at a time, so a change to (say) the Sites menu can't accidentally break
# WiFi setup or the uninstaller three thousand lines away.
#
# Migrated so far, grouped the same way the legacy menu groups them:
#   Core Settings: Sites & Page Timing, Display & Interaction, Timezone,
#     Hidden Site PIN, Password Protection & Lockout, WiFi,
#     Power/Display/Quiet Hours.
#   Addons: CUPS Printing (menus/addon_cups.sh).
#   Advanced: Diagnostics (menus/diagnostics.sh - system status/logs/
#     audio/network).
#
# Usage (once the kiosk has already been installed):
#   git clone <repo>
#   cd ubuntu-based-kiosk
#   ./install.sh
