Reset User Input
Form clears automatically after successful submission — no extra attributes needed.
Submit a message and the input clears itself, ready for the next one. There's nothing special to wire: the server re-renders the form from fresh state after the action, so the field comes back empty while the submitted values are kept in the list.
A plain form plus a list of submitted messages. No reset attribute, no client JS.

{{end}}Submit appends the message; because the input isn't bound to retained state, the
re-render starts it empty.
