 Next.js serves the default locale without a prefix and prefixes the others. For example, English uses `/about` and French uses `/fr/about`.
 
+Importing the values keeps both configurations in sync. If you hardcode `i18n.locales` or `i18n.defaultLocale` to values that differ from `gt.config.json`, `gt-next` prints a build-time warning that Next.js internationalized routing does not match the GT config file, because Next.js can then route to a locale that GT is not configured to translate. The comparison ignores ordering, so only the set of locales matters.

 Keep each page at the root of `pages`; do not add a `[locale]` segment:

Import the values from `gt.config.json` rather than repeating them, so the two configurations cannot drift; `gt-next` warns at build time when they disagree.
