+Image Mutations Module
+======================
+
+This package contains all available `ImageMutation` implementations.
+
+Each mutation represents a single, well-defined transformation that can
+be applied to a `ScanImage`. Mutations are designed to be composable and
+can be chained together using a pipeline (e.g. `returns.pipeline.pipe`).
