message: "'{NAME}' is a Next.js API, not from 'react' — import from 'next/{CORRECT}' instead"

description: |
  A Next.js-specific API is being imported from 'react'. This compiles but
  throws at runtime because react does not export these names.

  Common cases:
  - useRouter, usePathname, useSearchParams → 'next/navigation'
  - Link, Image, Script, Head → 'next/link', 'next/image', etc.
  - getServerSideProps, getStaticProps → page-level exports, not imports
