useServerFn
A POST from a click, then the loader runs again
The list below is loaded by listNotes() during render. Submit calls addNote() through useServerFn, which is the hook for calling a server function from an event. After the POST resolves, router.invalidate() runs the loader again, so the new note is read from the server rather than appended only in the browser.
