# Build Linux desktop packages (deb + rpm) for JellyTau.
#
# Produces bundles under src-tauri/target/release/bundle/{deb,rpm}.
# Runs on the existing Ubuntu builder image. NOTE: Tauri has no pacman bundle
# target — the Arch package is built separately with makepkg (scripts/build-arch.sh
# / Dockerfile.arch). `appimage` is also available if you want a portable bundle.
#
# Usage:
#   scripts/build-desktop-linux.sh                 # deb + rpm
#   BUNDLES="deb,appimage" scripts/build-desktop-linux.sh # subset / add appimage
#   OUTPUT_DIR=/app/dist scripts/build-desktop-linux.sh   # copy bundles out
