// Two targets rather than one. SteleKit holds the decisions — credential-file location and
// permission rules, host selection, request construction, response decoding — and depends on
// nothing, so the tests can exercise them as pure functions instead of spawning a process and
// scraping its output. The executable is ArgumentParser wiring and printing only.

    // structured concurrency without pinning anything newer than necessary.
