rich-display
Domain: Jupyter Integration
🎯 Motivation
Python objects can define _repr_html_(), _repr_png_(), etc. so Jupyter shows them as rich content instead of plain text.
📋 Concrete Example
A class with def _repr_html_(self): return '<b>Hello</b>' renders as bold text in the notebook.
🔗 Analogy
Rich display is a picture frame — your object chooses how to present itself, not just as a text string.
