This is the hub-forms Cloudflare Pages project (Angular staff console). Real app lands in Phase 4. If you can see this inside an iMIS page, the embedding path works (BUILD-PLAN P0.5).
Paste your iMIS base URL to confirm this origin is on the iMIS CORS allow-list. A resolved response (even 401/500) means CORS is allowed; a thrown network/CORS error means it is not.
