  #   * Ignored below: derived `Inspect` impls, the test fixtures themselves, and the
  #     structs Spark generates for DSL options and entity targets. None of it is code
  #     this project wrote or could test.
  #   * NOT ignored, though they report 0%: the DSL transformers. They run at *compile*
  #     time, when every fixture resource is built — so they are exercised by the whole
  #     suite, just not measurably. (The per-resource ones score higher only because
  #     `verify_language_test.exs` compiles resources inside test bodies.) Hiding them
