Get other styles working from existing json style formats.
Quite difficult to find good examples out there, just using this as a scratchpad... Some useful basic info at https://www.giserdqy.com/wp-content/guids/geoserver-2.14.0/user/styling/mbstyle/cookbook/index.html ... but a full example would be useful from somewhere also https://schwanksta.com/blog/vector-tiles-introduction-pt1 https://blog.sourcepole.ch/assets/2018/mvt-styling-foss4g18.pdf Possibly drawPath for paint and drawLine for stroke.
Also note you can click on the style json toggle for mapbox streets etc https://docs.mapbox.com/vector-tiles/reference/mapbox-streets-v8/
