+  // - Can skip over phases to find an input for a later phase.
+  // - If a later phase is outputting an asset and then stops outputting it,
+  //   it should stop shadowing an earlier asset and make it available.
+  // - Preprocessors that consume inputs versus transformers that just use
+  //   inputs.
+  // - What happens after a collision has occurred.
