  # The compiler core (`:wa_embedder`) is a separate hex package built with

  # WA_EMBEDDER_PATH (the nix dev shell sets it to "..") to build against the
  # sibling source instead of the published release. The core transitively
  # pulls the Erlang `:wa_parser` package — this wrapper does NOT depend on
