+name: FlashDeconv
+description: |
+  FlashDeconv is a high-performance spatial transcriptomics deconvolution method using
+  structure-preserving randomized sketching. It estimates cell type proportions for
+  atlas-scale and subcellular-resolution platforms (Visium HD, Stereo-seq, Xenium) with
+  linear O(N) scaling - processing 1 million spots in ~3 minutes on commodity hardware.
+  FlashDeconv provides a scanpy-compatible API (fd.tl.deconvolve) that stores results
+  directly in AnnData objects, enabling seamless integration with the scverse ecosystem.
