/**
 * moon-sighting — High-accuracy lunar crescent visibility and moon sighting calculations.
 *
 * Uses JPL DE442S ephemerides with full IERS Earth orientation for precise
 * topocentric Sun/Moon positions. Implements the Yallop (NAO TN 69) and
 * Odeh (Experimental Astronomy 2006) crescent visibility criteria.
 *
 * Quick start:
 *   import { getMoonSightingReport } from 'moon-sighting'
 *
 *   const report = await getMoonSightingReport(new Date('2025-03-01'), {
 *     lat: 51.5, lon: -0.1, elevation: 20, name: 'London'
 *   })
 *   console.log(report.yallop.category, report.guidance)
