    Interface LinesDualChunkIndex

    Internal index shape: the lines loader carries both vertex and segment chunk bounds. Only the segment side feeds SpatialQueryBuilder; the vertex side is kept so the loader can compute byte counts and (in the future) re-enable vertex-driven prefetching.

    interface LinesDualChunkIndex {
        segmentIndex: ChunkSpatialIndex;
        vertexChunkBounds: Float32Array;
        vertexChunkCount: number;
    }
