Building & deployment

To create a production build with static assets:

npm run build

This outputs the app to the dist/ directory with relative asset paths so it can be served from any URL prefix. Verify the output locally with:

npm run preview

Hosting

• Any static server: copy the contents of dist/ to your server's public directory.
• Vercel: the included vercel.json runs npm run build, serves dist/, and falls back to index.html for SPA routes after static assets are served.
