Ovidiu U	fdcf253ca7	Skip placeholder-coordinate postcodes (lat >= 90) in ONSPD import ... ONS marks non-geographic postcodes (no grid reference) with a placeholder latitude of 99.999999. The "Latest Centroids" export shipped ~12,789 such rows, which were imported as real postcodes pointing at lat 99.99 and would poison nearest-station distance maths. Drop them at ingest, with a test.
