Optional tooling, not part of the app
  tools/art/ uses FLUX.1 [schnell] (Apache 2.0) through Hugging Face
  diffusers to draw replacement pictures; tools/phoneme_check.py uses
  facebook/wav2vec2 phoneme models for checking clips. Nothing from these is
  shipped unless a parent installs the pictures they make.
