Description
Describe the issue
The matplotlib-inline backend provides the needs_background metadata which allows to force a light background under plot images to improve readability when using a JupyterLab dark theme. We should probably implement the same for the static image.
This will not work for the widget repr, but we could probably implement custom logic to mimick this behavior with the widget view.

Research direction
Read the referenced matplotlib_inline/backend_inline.py implementation at lines 226-239, then inspect ipympl's static image path and widget view. Implement the needs_background metadata behavior for static images; the issue notes that widget repr behavior may need separate custom logic.
