Fused by `_compute_clinical_markers(f0_features, voice_quality, prosody, spectral)`.

| Marker                   | Composite                             |
| :----------------------- | :------------------------------------ |
| `vocal_depression_index` | F0 range ↓, speaking rate ↓, jitter ↑ |
| `vocal_anxiety_index`    | F0 mean ↑, shimmer irregularity ↑     |
| `vocal_distress_index`   | Jitter ↑, shimmer ↑, HNR ↓            |
| `prosodic_flatness`      | F0 std ↓ (anhedonia marker)           |

Every marker reports `clinical_confidence` and the feature contributions that drove it. **The markers are signal for the clinician — not a diagnosis.**
