process.env.NEXT_PUBLIC_HEADLINE is being read inside a Client Component page (this file has "use client"), which means the value is inlined at build time and won’t reflect runtime env var changes. To achieve runtime configurability, read the env var in a Server Component (remove "use client" from this page or move the env read into the server layout/page) and pass it to ChatInterface as a prop (and force dynamic rendering for the route or layout).
