This walks you through wiring up remix-i18next in React Router framework mode with all the gotcha details: middleware setup, cookie-based locale detection, serving translation files from resource routes, and keeping client and server hydration in sync. You'll want this when you're past the basic tutorial phase and need to handle language switching, proper caching headers, and type-safe translation resources. The rules cover the full round trip from middleware detection through to bound t() functions in loaders and useTranslation hooks in components. It's opinionated about cookie persistence over URL prefixes, which makes sense for most apps but isn't universal.
