################################################################################
# menus/power_schedule.sh - "Power / Display / Quiet Hours" menu.
#
# Sixth menu migrated, and the biggest and riskiest so far: it writes
# systemd timers/services, a cron entry, and shell scripts that can power
# off the physical machine, blank the display, mute audio, and (via RTC)
# wake the machine back up on a schedule. Every write goes through
# $SYSTEMD_DIR / $CRON_D_DIR / $BIN_DIR (lib/config.sh) rather than
# hardcoded /etc/systemd/system, /etc/cron.d, /usr/local/bin, so tests can
# point them at a scratch directory - this file must never assume it's
# safe to actually mutate the real system just because it's running.
#
# Deliberately out of scope: the legacy dispatcher's "6. Test schedules &
# system" led into a shared diagnostics submenu (audio test, network
# test, keyboard test, ...) that isn't specific to scheduling and belongs
# with a future Advanced/Diagnostics migration instead. What *is* in
# scope - testing the schedule you just configured - stays here as the
# same inline "test now?" prompts the legacy menu already had.
#
# Bug fixed vs. the legacy configure_power_display_quiet: it refused to
# even open "Configure power schedule" when no RTC wake was detected,
# even though shutdown-only scheduling (configure_power_schedule's own
# fallback) never needed RTC in the first place. Also: none of shutdown
# time/wake time/display off/on/quiet start/end/custom Electron reload
# time were validated as HH:MM in the legacy menu (plain `read`, no
# format check) - a typo would silently produce a broken OnCalendar=
# value. All of those now go through ask_time.
#
# Depends on: lib/menu.sh, lib/config.sh being sourced first.
