# The configurator normally runs under this small PTY proxy so Ctrl-T can work
# as a global tools shortcut even while gum owns the terminal in raw mode. The
# child configurator keeps stdout on the existing stream (so generated config and
# logs behave normally), while stderr and /dev/tty traffic are relayed through the
# PTY. Pressing Ctrl-T kills the current configurator screen, opens Tools, then
# starts the configurator over at keyboard selection.
