Painting four pixel cities on one MacBook: DC took 81 min, Edinburgh just 19

Developer zsakib shared a chart of paint times for isometric pixel city maps generated on a single MacBook: each floor is one 1024px tile taking 10 seconds. Edinburgh took 19 min (10 tiles), Washington DC 81 min (50 tiles), and Miami was done in two passes (44 min South Beach + 27 min downtown). The actual painting is only 1h20 total — the real time sink was getting source data and landmarks right, with the whole project spanning about a week of on-and-off work.
