Calculate a traceable, versioned Vedic astrology chart with explicit modern true-Citra or historical ICRC/Newcomb/Woolard astronomy, strict IANA time handling, sidereal grahas, lagna, nakshatra, vargas, and isolated Parashari, Jaimini, or KP structures. Use for Jyotisha or Indian astrology chart requests before lineage-specific analysis and whenever reproducible chart JSON is required.
