Checks:
1. Frame-rate contract: T* == ceil(duration_s * 12.5) for varied durations.
2. Interface contract: shapes/dims/ranges of all outputs.
3. Emotion fidelity: top-1 agreement + JS divergence of student vs teacher
utterance probabilities over the val set; per-RAVDESS-emotion breakdown.
4. Dynamics: correlation between student intensity curve and teacher
max-prob proxy; frame-prob trajectory plot for one emotional utterance.
