LNBT hub coverage — Canada

From the US border through Baffin. The high Arctic islands are off this sheet. Product rule: largest nearby catalog city whose solar noon is within 15 minutes of the cell (~3.75° longitude). Compare with unconstrained largest-nearby and pure nearest. Generated 2026-10-06 · step 0.25° · land 23771 cells.

Working verdict: Some strip-like elongation remains. Product noon-cap 15 min: mean noon Δ 9.4 min (was 22.8 unconstrained). 44.2% of land cells change hub vs unconstrained; 11.0% still over cap (sparse catalog fallback).
