/**
 * Panchanga — Five Elements of the Vedic Almanac
 *
 * 1. Tithi     — Lunar day (Moon - Sun elongation, each 12°)
 * 2. Nakshatra — Lunar mansion (Moon / 13°20', 27 divisions)
 * 3. Yoga      — Luni-solar yoga (Moon + Sun, each 13°20')
 * 4. Karana    — Half-Tithi (each 6°, 11 types in a specific cycle)
 * 5. Vara      — Weekday from sunrise (not civil midnight)
 *
 * All angle arithmetic uses Decimal.js to eliminate IEEE-754 drift.
