/**
* Default 404 HTML body for the Pages Router.
*
* Used when a Pages Router request does not match any route (and the app has
* not supplied a custom `pages/404.tsx`). Mirrors the markup Next.js's
* `pages/_error.tsx` produces for a 404 response: a centered status / message
* pair plus minified theme CSS and dark-mode media query. The message string
* `"This page could not be found."` (note the trailing period) is the
* canonical body asserted by Next.js's deploy suite
* (`test/e2e/getserversideprops/test/index.test.ts`,
* `test/e2e/basepath/error-pages.test.ts`).
*
* Kept as a hand-rendered HTML literal rather than a React-rendered template
* because the Pages Router server entry is invoked from both Workers and the
* dev server before any React-renderer wiring is available for this path —
* matching the lightweight build-time strategy Next.js uses for its packaged
* `_error` static fallback. See:
* .nextjs-ref/packages/next/src/pages/_error.tsx
