Stream.toReadableStream and how I'm supposed to pair that with Stream.run*. Notably, this is at the intersection of Effect and non-Effect code (specifically a NestJS controller) where I need to return a NestJS "StreamableFile".new StreamableFile(Readable.fromWeb(...)) stuff is correct, I'm 99% sure. Interestingly enough, it does work when I change createWordExportStream() to return an Effect<Stream<>> instead of a stream directly, and then I Effect.runPromise() that.
