I noticed that Mapbox Studio has a way of creating & exporting styles (kinda like stylesheets but for maps). Do you know if those styles can be imported into a libre renderer like Maplibre, or if a similar tool/ecosystem exists for creating & sharing open-source map styles? Like if I wanted all roads to be rainbow-colored and rivers to be green.

In Mapbox Studio, the features all seem to be semantically tagged (e.g. this is a road of type X, a POI of type Y) and it makes styling a cinch. I know OSM has its own set of tags for features. Are these compatible (not sure if Mapbox Studio is using OSM data underneath)? Is there an established standard for this type of thing?

(ps TY again for answering my other question so thoroughly)
