/**
 * astroengine vargas -- Vedic divisional charts (vargas).
 *
 * A varga D-n divides each 30-degree sign into n equal parts and maps each part
 * to a sign by a classical (Parashari) rule. This covers the unambiguous,
 * textbook set: D1 (rasi), D3 (drekkana), D9 (navamsa), D10 (dasamsa), and D12
 * (dwadasamsa); the contested hora (D2) and unequal trimsamsa (D30) are left to
 * a later step. Rules (rasi/div 0-based; an "odd sign" is the 1st, 3rd, ... =
 * even rasi index): D1 the sign; D3 (rasi + 4*div); D9 element start
 * ([Aries, Capricorn, Libra, Cancer] by element) + div; D10 odd (rasi + div),
 * even (rasi + 8 + div); D12 (rasi + div). Computed from rasi = floor(lon/30)
 * and div = floor(within/(30/n)) so sign boundaries stay robust and
 * `Math.floor` matches Python's `math.floor`. Built on the validated sidereal
 * longitudes. Mirrors the Python reference (astroengine/vargas.py).
