# Build the J621 desktop packages into desktop/release/ — Arch (.pkg.tar.zst),
# Debian (.deb) and the Windows NSIS installer. Nothing is published: install
# the package locally, hand the files out, or attach them to a Gitea release
# manually. Use push_desktop.sh when the in-app update feed should get them.
#
# Usage: ./build_desktop.sh [--linux | --win | --all]
#   --linux   Arch + Debian packages only
#   --win     Windows installer only (cross-built with wine)
#   --all     everything (default)
