%description
Provides conversion among 'Seurat', 'SingleCellExperiment', 'AnnData', and
'Loom' single-cell data representations while preserving expression
matrices, cell and feature metadata, and dimensionality reductions when
supported by the target format. The package performs alignment and
validity checks during conversion and reports unsupported or unavailable
components rather than silently reconstructing them.
