The live demo loads the exact first-party CDN artifact the install
section hands out (/concierge/concierge.global.js, mirrored from the
SDK build), so this page proves the real embed rather than a bundled
copy of the source. It is loaded WITHOUT data-concierge so the auto-init
stays off; the module script below configures it once the global API is
ready (module scripts execute in DOM order).
