Menu item

A menu row with its own idle → pending → success/error lifecycle. It posts its enclosing form itself, crossfades between stacked states in place (the row never reflows), and once the success beat has played it refreshes the element named by refresh-target through Alpine-AJAX instead of reloading the page. This demo is live — the first row succeeds, the second is refused by the server and returns to idle for a retry.

A sticky rail of anchor links to sections already on the page. The page owns the sections and the anchors — this component is only the rail's presentation and the Alpine store that tracks which one is in view.
