packages/react/src/Dialog/Dialog.module.css:217

• [nitpick] Consider adding a Storybook example or unit test that demonstrates and verifies header overflow behavior under the new max-height constraint.

max-height: 35vh;

packages/react/src/Dialog/Dialog.module.css:217

• The PR title/description refers to "35%" but the code uses 35vh. If the intent was to limit to 35% of the container, consider using 35% instead of 35vh, or update the description to reflect viewport units.

max-height: 35vh;
