# Homebrew's install needs sudo for 10+ min across child processes. We grant a TEMPORARY
# /etc/sudoers.d/mac-setup (NOPASSWD) for the run and guarantee its removal three ways:
#   1. explicit removal after setup, 2. an EXIT trap (covers failures / a dropped ssh from here),
#   3. a 40-min self-destruct on the Mac itself (covers steel141 losing the network).
# $HOMELAB_PASSWORD is used once (piped, never in argv) to install the drop-in.
