Visualize Jupyter notebooks

[pitchhybrid]

I would like to suggest improvements to the viewing experience of Jupyter Notebook (.ipynb) files on the GitHub mobile app.
Jupyter Notebooks are widely used for data science, research, and machine learning workflows. While notebooks render reasonably well on the web version of GitHub, the mobile experience can be limited in terms of output rendering, navigation between cells, and overall readability.
Enhancing mobile support with better output rendering (including images and rich content), improved cell navigation, and a more responsive layout would significantly improve productivity for users reviewing notebooks on the go.
On the web, continued improvements to notebook diffs, large file handling, and richer HTML output support would also benefit collaboration.
Improving notebook support across both mobile and web would provide meaningful value to the GitHub community.
