    # file:line in a panic's backtrace at a fraction of full debug info.

  # The destination is one installation for macOS, Windows and Linux (D-56,

  # only here. `just check` (fmt, clippy, rustdoc, proofs' friends) stays
  # the Linux job's; these run the build and the tests. The job tells
  # which OS a failure is on; neither is allowed to hide the other.
