Raw terminal mode must be set by the parent process (the shell), not from inside SBCL. sb-ext:run-program subprocesses cannot reliably access the controlling terminal for stty operations. ./demo.sh sets raw mode via stty, runs sbcl --script demo.lisp, and restores terminal state on exit (EXIT, INT, TERM). demo.lisp no longer calls with-raw-terminal — it assumes the calling shell has already set raw mode.
