/**
 * astroengine rajayoga -- the lordship-and-aspect layer for Vedic yogas, and the
 * raja/dhana yogas built on it.
 *
 * Layers: house lordship (traditional ruler of each whole-sign house from the
 * Ascendant); graha drishti (every planet aspects the 7th sign; Mars also 4/8,
 * Jupiter 5/9, Saturn 3/10); association (conjunction, mutual aspect, or
 * parivartana exchange); then raja yoga (a kendra lord 1/4/7/10 associated with
 * a trikona lord 1/5/9), dhana yoga (two wealth-house 2/5/9/11 lords), and the
 * yogakaraka (a planet ruling both a pure kendra 4/7/10 and a pure trikona 5/9).
 * Definitions follow BPHS, validated against the named source in
 * `validate_jyotish`. Mirrors the Python reference (astroengine/rajayoga.py).
