TerrainTileFetcher

actual class TerrainTileFetcher(pmtilesUrl: String) : AutoCloseable(source)

Fetches individual tiles from a remote PMTiles archive by range request — never the whole archive, just the bytes of the tile asked for. Backed by ch.poole.geo.pmtiles:Reader (MIT-licensed), the same library the base offline layer uses for Protomaps; here it's pointed at Mapterhorn's Terrarium elevation archives instead.

A plain Java library, so its wrapper is duplicated between androidMain and jvmMain rather than living once in commonMain — see this module's build.gradle.kts for why.
