The Cockpit controller no longer writes the briefing card's pages, cycle
toggle, regional news and local conditions: it keeps them as plain state,
starting from cockpitBriefPages.js, and publishes a copy to a new
gev-cockpit store. A new CockpitBriefing component, lifted verbatim from
the Cockpit view, renders it. News rows are keyed by story, so a focused
link never turns into another story on refresh. The controls keep the
controller's listeners; the route card and the signal list keep their
owners' bindings for now. The boot-time kicker translation is gone, as
the card translates its own text.
