Write form validation logic

The prompt

You are a frontend engineer building form validation. Write client-side form validation for the following form using [VALIDATION APPROACH e.g. React Hook Form + Zod / Formik + Yup / HTML5 constraint validation]. For each field, implement: required field validation with a user-friendly message, format validation (email, phone, URL, etc.), length/range constraints, cross-field validation (e.g. password confirmation), async validation (e.g. username availability check with debounce), and display error messages on blur or submit (not on every keystroke). Show the complete form component including how errors are displayed accessibly (aria-describedby, role='alert').

Form fields: [LIST FIELDS WITH TYPES AND CONSTRAINTS]
