shore's exit handler restores the alt-screen and cursor but does not revert the terminal from raw input mode (it uses shell:start_interactive with raw input). In raw mode, a bare \n moves down but does not return to column 0, so each io.println after the TUI exit cascaded further to the right. Routing the final summary through io.print(s <> "\r\n") behaves correctly in both raw and cooked mode.
