Static outdoor layers
Static layers are versioned snapshots served as raster or vector tiles from PMTiles archives. 0.2 credits per tile; metadata is free.
GET /v1/static/{layer}/{z}/{x}/{y}.{mvt|png}GET /v1/static/{layer}/metadataEmpty tiles return 204. The metadata document carries format, minzoom, maxzoom, bounds, the vector source-layer names and attribution, so nothing needs hard-coding.

Slope tiles are value-encoded like weather tiles: decode degrees from the red channel and colour with your own ramp (or the stops in metadata).
