### SubmitBar — submit (and cancel) with pending state

Submission fires only when every check on the surface passes. Hand-pick the answers you need into
`context`. To report a server-side verdict afterwards, reply with `updateDataModel` on the path you
want written — bind a `Callout` or the field's own error to that path when you build the form.

| prop           | type       | required | notes                                                          |
| -------------- | ---------- | -------- | -------------------------------------------------------------- |
| `submitAction` | action     | yes      | `{"event":{"name","context",...}}`; name it after what happens |
| `submitLabel`  | string     | no       | e.g. `"Create account"`; default localized "Submit"            |
| `cancelAction` | action     | no       | renders a quiet cancel button                                  |
| `cancelLabel`  | string     | no       |                                                                |
| `pending`      | `{"path"}` | no       | bind and set true while you process; the bar disables          |
