Removes the pick-up mode (it never rendered: data-attr-hidden is not a Datastar attribute), the per-column drop buttons and the per-card select+move form. Cards show a grip and a grab cursor; the column under a drag lights up; a native Move popover lists the other columns as plain forms, so it works by keyboard, touch and without script. /move answers Datastar with the fragment and a plain post with a redirect; both show 'Moved X from A to B · undo'. check-in: 110001e141 user: dmestas tags: trunk
