Astro is a modern site builder with web best practices, performance, and DX front-of-mind.

import type { FetchState } from '../fetch/fetch-state.js';
import { type CompiledI18n } from './handler.js';
/**
 * Runs {@link finalizeI18n} and, when it replaces the response with a
 * null-body 404/500 (e.g. a locale-less path under `pathname-prefix-always`),
 * renders the error page for it — the reroute `handleRequest` performs after
 * `finalizeI18n` on the standard path. Responses passed through unchanged
 * are returned as-is.
 *
 * Used by the composable `astro/fetch` `i18n()` entry point, where there is
 * no surrounding `handleRequest` to supply this fallback. Kept out of
 * `handler.ts` because that module is reachable from the client-importable
 * `astro:i18n` virtual module, which must not pull in error-page rendering.
