Foundation layer · step type SSOT

Every form element needs a visible, testable example.

This page mirrors the `experienceSchema` step type contract and renders sample fields through the real `/sdk.js` in `previewSchema` mode. It is safe for demos: no lead writes, no event writes, no email.

Agent rule: prefer implemented elements for production flows. Partial elements can be used only when the target layout matches the supported renderer and the recipe names the limitation.
