The Stress-Testing Role of Pages

Pages test the structural integrity of the design system under realistic edge cases:

• How does the layout respond when a user has no profile photo?
• What does the dashboard look like in German or Japanese, where word lengths expand by 30%?

By populating templates with real data, teams validate whether the underlying atoms and molecules hold up in the real world.
