Recommend dark-sky sites near a location, ranked by whether the drive is worth it.
Use for "where should I drive to stargaze near X". Sites are grouped by
drivability (how far), then ranked by a drive-worth score combining the
best weather window over the next 7 nights, how much darker the site is
than the user's location, and drive time. Drive times are approximate
(straight-line x 1.3), not routed.
Args:
lat: Latitude in decimal degrees (-90..90).
lon: Longitude in decimal degrees (-180..180).
limit: Max sites to return, 1-12 (default 5).
Returns {ranking (methodology note), tiers:[{tier, label, hint, sites:[...]}],
nearest_km, uncertainty_note, attribution} — sites grouped into drivability
tiers. Include the methodology note when presenting — it explains the
ordering honestly.
