# Assemble the getlibreportal docroot — the website + install.sh + release
# channels — into the served data dir. Run on a FULL repo checkout (build/release
# machine), since it needs ../../site and ../../dist (both export-ignored, i.e.
# not in release tarballs).
#
# Usage: publish.sh [TARGET_DIR]
#   TARGET_DIR defaults to ./data (next to this script). On a host where the app
#   is installed, pass its live data dir, e.g.:
#     containers/getlibreportal/publish.sh /libreportal-containers/getlibreportal/data
#
# Layout produced:
#   <target>/            ← built website (repo: site/)
#   <target>/install.sh  ← bootstrap installer (repo: install.sh)
#   <target>/<channel>/… ← release manifests + tarballs (repo: dist/<channel>/)
