# Optional: auto-deploy when pushing to a bare repo on the host.
#
# The normal workflow is scripts/deploy.sh from the development machine; this
# hook is for the variant where the host also has the toolchain and a working
# checkout. Install as hooks/post-receive in the bare repo, make it
# executable, and set WORK_TREE to a checkout whose origin is that bare repo.
