    // --- How to run a single test or test class ---
    //
    // Run all tests in one class (e.g. BorgTests):
    //   mill hardware.borg.test.testOnly borg.BorgTests
    //
    // Run a single test method (class glob before --, full utest path after --):
    //   mill hardware.borg.test.testOnly borg.BorgTests -- borg.BorgTests.hw_flusher_autonomous
    //
    // The part after -- is the utest query selector (full dotted path from package root).
    // utest uses sbt.testing.Framework as its interface; `-- <path>` is passed as
    // args(0) to BaseRunner, which filters both the class and the individual test.
    //
    // Note: `mill hardware.borg.test -- borg.BorgTests.foo` does NOT work —
    // mill does not forward -- args to the sbt testing runner that way.
