/* Curated major ports for matching AIS destination strings. AIS ShipStaticData.Destination is free-text typed by the crew — typically contains a port name or a UN/LOCODE ("CNSHA" = Shanghai, "NLRTM" = Rotterdam), sometimes both, sometimes a multi-stop string like "SHANGHAI>SINGAPORE". Match rate from this list is ~60-70% of the destinations we see in practice. Each entry: [lat, lon, canonicalName, ...aliases]. Aliases include the 5-char UN/LOCODE, common English name, and a few common abbreviations / variants. Uppercased at lookup time. Exposes: window.resolvePort(destStr) → {name, lat, lon, alias} | null */ (function () { const PORTS = [ // East Asia — world's biggest container hubs [ 31.230, 121.474, 'Shanghai',
