4. Run `pnpm i18n` to generate translations for all supported languages.
5. Use the `useTranslation` hook from `react-i18next` to access and display translated text in React components.
6. Specify the appropriate namespace when using the `useTranslation` hook to retrieve translations from the correct file.
