LIGHTHOUSES OF THE WORLD: DATA
https://thestatesmansledger.org/lighthouses

world.json           Every lighthouse as a row: [longitude, latitude, pattern, region, range (nm), phase].
                     pattern indexes "patterns": one period of the light as [seconds, level 0-1, colour],
                     colour indexes "colours" (W white, R red, G green, Y yellow, Bu blue, Vi violet,
                     Or orange, Am amber). pattern -1 means no light is listed. region indexes "regions".
                     phase is a fixed per-light offset so lights do not all flash together.
regions/<slug>.json  Full details per region: name, country, characteristic in chart notation, range,
                     light height (m), structure, sectors, year first lit, and the source records
                     (OpenStreetMap IDs, NGA List of Lights and USCG Light List numbers, Wikidata item).
summary.json         Counts per region and country.
