"""Smoke test: load the bundle, embed the shipped fictional texts, generated test images and generated audio clips,
compare with the fp32 reference vectors and check that every query finds its own image / clip first.

    python3 smoke_test.py [--bundle ../model] [--compute ane] [--image-compute gpu] [--audio-compute gpu] [--text-only]
                          [--no-audio] [--cleanup-temp] [--reference ../tests/smoke-reference.json ...]

Exit code 0 = every cosine >= its threshold (0.999 texts, 0.998 images, 0.9995 / 0.995 audio clips), all values
finite, every query at rank 1. `--text-only` runs only the v1.0 text reference and loads neither the vision nor the
audio asset; `--no-audio` skips the audio reference. The first run of a new executable (here: your python binary)
specializes the assets for the Neural Engine: expect a few minutes. Later runs load in about a second.
