Multi-step Signup Form (3-step Wizard)

Challenge summary

Build a 3-step signup flow in Vue 3 that collects basic info, address info, and shows a summary with a final submit action. Each step should be validated before the user can proceed.

What you'll practice

• Render a 3-step signup form as a small wizard-style UI.
• Step 3: Summary + Submit (show all collected data and allow submission).
• Provide a "Next" button to advance to the next step.
• "Next" must only be enabled when the current step is valid.
• Provide an optional "Back" button to navigate to the previous step (except on the first step).
