NaN != null is true, so all null-checks let NaN coordinates through to Leaflet which crashes with "Invalid LatLng object: (NaN, NaN)". Server: sanitize coordinates with Number.isFinite() before sending — NaN from bad grid lookups or prefix estimates now becomes null. Frontend: replaced all spot/path coordinate guards from spot.lat != null → Number.isFinite(spot.lat) in WorldMap.jsx (placeSpots, DX paths) and AzimuthalMap.jsx (POTA, WWFF, SOTA, WWBOTA, DX marker, spotter paths).

Railway's build cache couldn't compute checksum for the specific file path rig-listener/rig-listener.js. Changed to COPY the whole directory instead, which avoids the cached reference. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
