/**
 * astroengine ashtottari -- the Ashtottari dasha, a 108-year conditional dasha.
 *
 * Eight lords rule in order -- Sun 6, Moon 15, Mars 8, Mercury 17, Saturn 10,
 * Jupiter 19, Rahu 12, Venus 21 years (totalling 108). Unlike Vimshottari the
 * nakshatra-to-lord mapping is in irregular groups, and the elapsed portion of
 * the first period is measured across the lord's whole multi-nakshatra span.
 *
 * Convention: the JHora/PVR Narasimha Rao mapping (the PyJHora implementation),
 * which the texts vary around; the lord ranges and across-span balance are
 * reproduced from it, validated against the named source in `validate_jyotish`
 * rather than asserted. Mirrors the Python reference (astroengine/ashtottari.py);
 * the golden fixtures pin the two together.
