New components/LiveView.tsx renders the default landing at "/": full-bleed MapView (rail + legend from chunk 5) plus a new TimeScrubber strip below it — real call-density bars over the selected 1h/6h/24h/7d window, tinted by the worst severity in each bucket, playhead pinned to NOW. The playhead doesn't scrub yet; that needs `resolved_at` on incidents, which doesn't exist server-side (blocked chunk 13, in DEFERRED.md) — the density data itself is live, not a fixture. Distinguishes the two empty states UI_REDESIGN.md §4 calls out: a configured-but-quiet org (nodes online, zero active incidents) now shows "Listening — last check-in Xm ago" instead of rendering nothing, separate from the zero-node case (chunk 10's Activation screen). app/page.tsx's HomePage now renders LiveView directly for a signed-in, provisioned user instead of the chunk-4 interim redirect to /incidents. Per UI_REDESIGN.md chunk 6.
