This template uses next-intl for localized routing.

• Default Locale: en
• Supported Locales: en, zh
• Routing: Routes are automatically prefixed (e.g., /en/dashboard).
• Configuration: Easily add public routes in proxy.ts to skip authentication.

Build the optimized production image:

docker build -t next-shadcn-template .

The image leverages Next.js standalone output to ensure the smallest possible footprint.
