Global i18n at Scale

Global products need more than translation: locale-aware formatting, RTL layouts, regional CDN delivery, ICU plurals, and jurisdiction-specific compliance copy.

This module covers lazy locale bundles, CSS logical properties for RTL, ICU via FormatJS/next-intl, compliance copy workflows, and pseudo-localization CI.

Staff interviews ask how you ship 30 languages without bloating the bundle or breaking layouts.

Staff track module: extends Frontend System Design i18n section (Module 17) with operational depth.
