Achieve smooth UI/UX with Unified Components Across Web and Mobile

Three platforms, one Button. Same hover state, same focus ring, the same 16px radius. When it works, it's the closest thing to a free lunch engineering has ever shipped — you write <Button> once and your web app, your iOS build, and your Android build all pick up the change.

When it doesn't work, you find out at the worst possible moment. Your designer hands you a Figma with a 12px radius update and you discover that "cross-platform" was a wish, not a fact. The Button on web rounded to 12. The Button on iOS is still 16. The Button on Android is whatever the platform defaults decided. You have three components now, pretending to be one.
