The vault card lives where notifications were — header with sync pill
(clean/ahead/behind/dirty), today's note entry, five freshest notes,
cold start and push rows — over the notification list. Lens.qml owns
souveraine-lens the way Face owns the rig: one socket, event lines up,
no vault access of its own. Kiyoshi's slash grammar and tool registry
are noted for the fuller app; the micro view only opens and plants.
