Function guessStyle

Inspect a tileset and return the most appropriate MapLibre style.

source is either the URL of a TileJSON document, which is downloaded (relative tiles are resolved against the document), or a TileJSON object the caller already holds — a tile server has one in memory from its container's metadata — which is used without any network access (relative tiles are resolved against options.urls.base). The caller's object is not modified.

Styles by tileset:

• Shortbread vector tiles → full osm() style
• OpenMapTiles or Protomaps vector tiles, with that schema injected (options.schemas) → its style
• Vector tiles matching a caller's own injected schema → that schema's style
• Unknown vector tiles → inspector style (one color-coded fill+line+label per source-layer)
• Raster tiles with satellite name hint → satellite() style
• Other raster tiles → minimal single-layer raster style

Never throws — an invalid argument, a failed download or a malformed document all yield a blank (but valid) StyleSpecification.
