open suspend override fun openVectorTileStore(contentKey: String, levelSet: LevelSet, cachePolicy: CachePolicy = CachePolicy.UNBOUNDED, displayName: String? = null): TileStore
Open (or create) a TileStore for vector-tile data — backed by data_type='vector-tiles' (im_vector_tiles_mapbox extension). Used by MVT layers that store raw protobuf bytes per tile.
See openImageTileStore for displayName semantics.
