A fictional storefront. Every pixel of this site exists to test embedding.
Self-login: pick a demo user and the widget emails them a one-time sign-in code. Zero integration — the customer site pastes only the loader.
The launcher bubble appears bottom-right (drag it, click to open). The widget sends a 6-digit code to the chosen address; enter it to sign in.
Mint an identity: curl -X POST <origin>/api/engine/embed/sign-test -H "Authorization: Bearer <admin JWT>" -d '{"tenant":"dash","userId":"demo_1","email":"demo@upcai.info","role":"member","entityId":"2197"}'
— the signed blob (not the secret) is what a customer backend renders into their page.
