-Modified the interaction logic for selecting upgrade options. You can now cancel the selection after you pressed the left mouse button, just by releasing it after moving the mouse out of the selected upgrade card. (Previously: the clicked upgrade item was always selected no matter where you released it.) -Modified keyboard interaction logic: from press to select upgrade to release to select upgrade.
