Mvt
Decides how each MVT feature should be drawn: for polygons and lines, what ShapeAttributes to apply; null skips the feature entirely.
Two implementation styles ship in the package: hand-coded (DefaultMvtStyle, OpenTopoMapMvtStyle) and rule-based with filter/zoom support (MvtRuleBasedStyle, built by the mvtStyle DSL).
Implementations should be pure and stateless — MvtVectorLayer resolves the style once per feature during background tile assembly, off the render thread.

Properties
Solid base under every fill — the Mapbox background layer. Fills gaps MVT has no polygon for (bare rock, street interiors, highway corridors); null (default) shows whatever is beneath the layer. See Z_BACKGROUND.
Functions
Resolve attributes for one feature. layerName is the MVT layer (e.g. water, transportation, building); geometryType gates polygon-vs-line attribute choice. properties is the inflated feature property map.
Optional paint order within a tile. Features with smaller zOrderFor paint first, features with larger values paint over them. Default 0 — every feature shares the same z-layer, and the order falls through to MVT-server-determined layer iteration order (good enough for OpenMapTiles-schema servers that already order water → landuse → roads → buildings sensibly).
