# ABOUT ME
# Installs the Auto Radiator mod into Cosmoteer's user Mods folder.
#
# Why it exists: Cosmoteer loads mods from the user profile directory, which on
# a Proton install lives deep inside the Steam compatdata prefix and is awkward
# to find by hand. This script locates it, validates the mod against the
# installed game data first, and copies only the files the game needs.
#
# Usage:  ./install.sh            install (validates first)
#         ./install.sh --uninstall  remove the installed copy
