Full details: Type-Safe Boundaries

Explanation

The PR newly consumes site.locale from the external site response without validation. The changed calls pass it directly to formatPrice in ProductsSection, GiftPage, GiftSuccessPage, and OfferPage; formatPrice calls toLocaleString(locale), which throws for invalid locale tags. GhostApi.site.read() returns res.json() without schema parsing, and existing code documents that the site locale is stored unvalidated (for example, en_US can be rejected by Intl). This is a changed behavior and can expose an invalid API value during render.

Resolution

Validate the site API payload at its boundary with a Zod schema before placing it in AppContext. Validate locale as an optional string accepted by Intl or normalize invalid values to a safe fallback such as en. Pass only the parsed or normalized locale to formatPrice and formatGiftValue. Add a test for an invalid locale to confirm that rendering does not throw.

Full details: New Files Are Typescript

Explanation

It is not in an exception directory. The PR also adds no other JavaScript-family files; pre-existing .jsx files are only modified.
