Ascendant Calculation 1. Interfaces and Constants We start by defining the necessary constants and the expected structure for the input data. // – – 1. CONSTANTS AND INTERFACES – – interface Coordinates { latitude: number; longitude: number; } interface BirthData extends Coordinates { year: number; month: number; day: number; hour: number; // Local Time (24-hour) minute: number; timeZoneOffset: number; // e.g., 5.5 for IST } interface LagnaResult { siderealAscendant: number; jd: number; // Julian Day (for subsequent planet calculations) ayanamshaDeg: number; } // Lahiri Ayanamsha Constants (Simplified Linear Model for Demonstration) const AYANAMSHA_CONSTANTS = { // Approx Lahiri value on
