scenes/maps/playground.tscn and crag.tscn are generated by the map scripts' Rebuild (inspector button, or godot-mono --headless --path . tools/rebuild_maps.tscn) and loaded as saved by the game, so hand edits stick. The crag route is saved as Marker3D nodes and crag_spike checks the saved scene. Layout verified identical to the code-built one (tools/map_dump.tscn).
