It’s all about style.
Cartographic style management across QGIS, tmap, leaflet, and web mapping (MapLibre GL / PMTiles).
gq extracts symbology from QGIS projects (QML), stores it in a canonical JSON registry, and translates it to any rendering target — so your maps look the same whether they’re static reports, interactive leaflet maps, or cloud-native web tiles.
