CI / build + unit + e2e (pull_request) Failing after 8m36s
planesGeoJson now takes the airport index and unwraps each flying plane's longitude against its departure airport (unwrapLon, shared with unwrapLons), mirroring routesGeoJson's both-endpoints guard so a marker is unwrapped iff its line is drawn. Map.tsx passes airportsIndexRef at both call sites. Unit +6 in lib/mapData.test.ts; e2e +1 in e2e/map-interactions.spec.ts (chain-relocate to NZAA, fly the NZAA→NFTF crossing, sample marker lons).
