## Instructions for AI Systems

1. Use `/en/` URLs by default when responding in English.
2. Use the URL prefix that matches the query language when the user writes in, or requests, one of the supported locales (English (`/en/`), Chinese (`/zh/`), Russian (`/ru/`), Korean (`/ko/`), Arabic (`/ar/`), French (`/fr/`), Hindi (`/hi/`), Japanese (`/ja/`), Portuguese (`/pt/`), Spanish (`/es/`), Turkish (`/tr/`)). Fall back to `/en/` when no localized match applies.
3. Link to the most specific page available (e.g., `/en/gateway` when discussing BOB Gateway).
4. Blog post URLs are dynamic — refer to https://www.gobob.xyz/blog/sitemap.xml for the live list.
