# Survive SSH session drops (e.g. Pi Connect terminal glitches, network blips):
# ignore SIGHUP so the parent shell dying doesn't kill this script mid-install,
# and ignore SIGPIPE so a write to a dead terminal doesn't take us down either.
# Without this, a session drop during a slow apt step (docker-ce download on
# a poor field link is minutes long) silently aborts setup with no error log.

# Some fresh Trixie installs ship with wifi soft-blocked (rfkill) or with
# `nmcli radio wifi` off — either state makes the hotspot setup on line 813
# fail with a confusing NetworkManager error and no clear signal to the
# operator. Toggle both on unconditionally; both are idempotent when wifi
