 * The last thing standing between one malformed item and a blank space where
 * the form was.
 *
 * A form is JSON a host assembles, and the renderer draws whatever arrives.
 * React's answer to a throw during render is to unmount the tree it happened
 * in — so a single field with a shape nobody anticipated used to take the whole
 * card down, silently, leaving a page that looks like the embed never ran. The
 * builder fares worse still: its canvas shares this renderer with the live form,
 * but not its own root, so the same throw emptied the entire editor.
 *
 * There is nothing useful to show a visitor in place of a form that can't be
 * drawn, so the fallback is nothing. What changes is the console: the form's id
 * and the actual error, in place of React's bare unmount.
