Internationalization I18n

This handles multi-language support across the full stack, from i18next and React-Intl for frontend work to Python's gettext for backend apps. You get translation workflows with interpolation and pluralization, proper date and currency formatting with the Intl API, and RTL language support using logical CSS properties. The examples are practical, covering everything from basic string translation to relative time formatting. One thing worth noting: it pushes you toward logical properties and pseudo-localization testing from the start, which saves you from painful refactoring later when you add Arabic or Hebrew support. Good coverage of the boring but critical details that make internationalization actually work in production.
