  What to do
    dynamic-render
      This page is rebuilt for every request and never cached at the edge. In
      Next.js one `await headers()`, `cookies()` or `searchParams` read in a file
      the whole app shares — the root layout, not-found.tsx, or an error boundary
      — flips every route to dynamic with no build warning and no visible change
      in a browser. Look there before you look at the route itself. If per-request
      rendering is intended here, pass --allow-dynamic.
