  # The :hologram OTP app starts automatically under `mix test` and its

  # exists at `<build>/lib/hologram/priv/page_digest.plt`. That file is
  # normally produced by `mix compile.hologram`, which requires a working
  # `npm install`. To let the test suite boot without the full asset
  # pipeline, we write an empty PLT (an erlang-term-encoded empty map) to
  # that path before `mix test` runs if one isn't already there.
