@ifc-lite/solar — solar position, sunrise/sunset and 3D sun-path geometry.
Pure, dependency-free math: given a site latitude/longitude and an instant,
compute where the sun is, and generate the sampled curves for a 3D
sun-path dome (day paths, hourly analemmas, graticule). Renderer-agnostic —
outputs are plain angles and ENU unit vectors.
solarGeometry(date:Date):SolarGeometry
Date-only solar geometry (declination + equation of time). These vary
slowly over a day, so sun-path samplers can compute them once per day and
reuse them across many hour-angle evaluations.
