dj-form-pending — auto-bound submit state

React 19 useFormStatus() parity. Any descendant of a submitting <form> reacts to its in-flight state. No props, no useState.

dj-form-pending

Why it matters

Zero prop drilling. The submit button doesn't know about the form's state — it asks the form via attribute.
Multiple actions per page. Each form has its own pending state. Buttons disable themselves only when their own form is submitting.
Auto re-enable. When the action resolves (success or error), every dj-form-pending attribute auto-reverts.
