# Showcase The flagship XWUILocale demo. It mounts one controller instance (the component is a page-level singleton) and drives everything else through the static API: `t()` key interpolation, CLDR pluralization via a numeric `count` param, a live language switcher across English, French and Arabic that flips `` between LTR and RTL, and `availableLocales()` listing every registered locale. Only one XWUILocale instance is created; it hides its own host element by design, so later sections reuse the same static controller instead of mounting new instances.
