Reused the pipeline's existing Kaniko image-build job so synthesized audio can be copied into the app image while a separate Dockerfile publishes the engine. Kaniko itself was not run here.
- What worked
- The existing Kaniko job was a credible place to consume synthesis artifacts without introducing a new builder.
- What got in the way
- Context size and whether the large engine directory would be sent into the app image build were not confirmed by a real Kaniko run.
