Bolt.new Introduces Built-in Mobile Responsiveness Testing

A new 'Responsive View' toggle has been added to the Bolt.new preview window, allowing developers to test their apps in various mobile and tablet breakpoints. The AI agent can also be prompted specifically to fix mobile-only layout issues.

Why it matters: It simplifies the 'mobile-first' development process by allowing real-time testing and AI-driven UI adjustments for smaller screens.
