# A stale `make run` keeps holding $(PORT) and answers with the previously built
# code; a second run that fails to bind only logs the error and serves nothing,
# so requests silently hit the old binary. Free the port first — killing the
# listener also makes its parent `go run` exit. The dev container has no
# lsof/fuser, so resolve the listener through /proc.
