# Target level in the Target window (2026-10-04): install the staged DLL and EQUI_TargetWindow.xml into one client
# folder (default: Trevor's desktop client) for testing. Backups: <file>.bak-targetlevel (made once, from whatever is
# there; a missing original is remembered as <file>.bak-targetlevel-absent and removed on revert).
# Run on the desktop:  bash install_desktop.sh [client_dir]     (after copying this folder there)
# Launch with the "(Direct)" launcher: the Patcher launcher puts the shipped (live) DLL back.
# Undo: bash install_desktop.sh --revert [client_dir]. The only complete undo until published: the Patcher launcher
# restores the DLL but leaves EQUI_TargetWindow.xml (not a patcher file yet), which with the live DLL shows
# "Unknown Label900" in the Target window.
