Multi-step Signup Form

Challenge summary

Build a 3-step signup flow in React that collects basic info, address info, and then shows a read-only summary before submitting. Each step should only advance when its inputs are valid.

What you'll practice

• Render a multi-step signup UI as the main component.
• Step 1 (Basic info): collect name and email.
• Step 2 (Address info): collect street, city, country, and an optional postal code.
• Step 3 (Summary): display a read-only summary of all collected fields and a final Submit button.
• Use controlled inputs for all fields (values come from component state).
