Pick a HEA, language, and audience. Copy the enterprise or agency page with that HEA in the ask bar, the bottom-left pop-up, and the side panel. Anyone with the link can talk to the HEA — same as today’s preview and hea_simple. This is a shareable demo, not a secret.
This HEA is not published. The commercial page still works (same as hea_simple). “See it on your website” stays hidden until a published domain exists.
