T8b949e/**

* The Mapbox Vector Tile schema (mapbox/vector-tile-spec, v2.1) — the format every layer of a Protomaps PMTiles basemap

* is stored in. Decoded with `kotlinx-serialization-protobuf` against hand-written `@Serializable` classes rather than

* a generated or vendored parser: the schema is nine fields across four small messages and has been stable since 2015,

* and this keeps the offline-map feature off an unpublished dependency (the natural Java vector-tile parsers on GitHub

* — e.g. ElectronicChartCentre/java-vector-tile — never shipped to Maven Central; JitPack would be the only way to pull

* them in, which is a supply-chain trade this feature doesn't need to make for a ~60-line schema). Field numbers below

* are copied verbatim from https://github.com/mapbox/vector-tile-spec/blob/master/2.1/vector_tile.proto.
