 Enhancements
 ~~~~~~~~~~~~
 - Add unified interactive macro table for dataset summary page with 58 metadata columns, SearchPanes filtering, paradigm distribution bar, and CSV export (:gh:`1043`).
+- Add rich HTML repr for preprocessing pipeline transformers: pipelines now render as interactive sklearn diagrams in Jupyter notebooks and sphinx-gallery docs, showing the three-stage flow (Raw, Epochs, Array) with readable step names, event lists, and key parameters instead of raw dict dumps (by `Zach Munro`_ and `Bruno Aristimunha`_).
 - Expose ``motor_imagery`` and ``mental_arithmetic`` keyword-only parameters on :class:`moabb.datasets.Shin2017A` (default: MI=True, MA=False) and :class:`moabb.datasets.Shin2017B` (default: MI=False, MA=True), allowing users to load both conditions simultaneously while preserving backward compatibility (by `Bruno Aristimunha`_)
 - Add resting state annotations and EMG channel support to :class:`moabb.datasets.Lee2019` resting state runs for BIDS export compatibility (by `Bruno Aristimunha`_)
 - Skip zip extraction in :class:`moabb.datasets.GuttmannFlury2025` when files are already extracted, with ``/scratch`` fallback for NFS filesystems on compute nodes (by `Bruno Aristimunha`_)
