Description: Projects gene expression onto the plane of a biological
        network and draws it as a landscape: a Gaussian-kernel weighted
        surface on an absolute scale where 0.5 means no change. Regions
        of the landscape are tested by permutation, either conditional
        on the network and layout (node-label shuffling, maximum
        regional mass) or against biological replication (sample-label
        permutation, with blocking). Graph-native tests complement the
        landscape: threshold-free cluster enhancement on network
        components, Moran and Getis-Ord autocorrelation, Laplacian
        smoothness, Freedman-Lane residual permutation with covariates
        and degree-preserving rewiring nulls. Pseudobulk workflows for
        single-cell RNA-seq permute donors rather than cells. Adapters
        read DESeq2, edgeR, limma and Seurat results,
        SummarizedExperiment objects and STRING networks. A Shiny
        interface covers the interactive visualization.
