The old remote pass kept every non-large fixed-wing row with no large airport within 1000 km, so regions without big cities (central Australia, Canada edges) got filled with dozens of tiny strips.

scripts/build-world-airports.mjs now greedily thins the same candidate pool to one special per ~1000 km region: candidates sorted by priority (scheduled service, then type rank medium < small < seaplane, then numeric id), accepted only if at least REMOTE_RADIUS_KM from every already-accepted special. Subsumes and deletes the old 40 km remote clustering; large-airport pass and all guards unchanged.

Regenerated data/airports_world.csv: 1483 → 1161 rows (1119 large unchanged, specials 364 → 42; min pairwise special distance 1001.6 km). New unit test pins the pairwise-sparsity invariant on the committed dataset (lib/airports.test.ts); no runtime code changes in lib/airports.ts.

v0.68.0 — see CHANGELOG.md.

Greedy sparse selection replaces the blanket 1000km-from-large filter that
over-filled central Australia / Canada edges with dozens of tiny strips:
candidates sorted by scheduled service, type rank (medium < small < seaplane),
numeric id; accepted only if >= REMOTE_RADIUS_KM from every already-accepted
special. CSV: 1483 -> 1161 rows (1119 large unchanged, specials 364 -> 42).
New unit test pins the pairwise-sparsity invariant on the committed dataset.
