def classify_body_type(wrist_cm, height_cm):
    """
    Classify somatotype using the wrist-to-height ratio.

    Thresholds (empirical):
        ratio < 0.1035  → Ectomorph  (small frame)
        ratio > 0.1160  → Endomorph  (large frame)
        otherwise       → Mesomorph  (medium frame)

    Parameters:
        wrist_cm  - wrist circumference in centimetres
        height_cm - height in centimetres
