// HOMECORE-UI bootstrap + shell + router — ADR-131 §5.
//
// Builds the Cognitum-shell top nav (Framework | Guide | Cog Store |
// HOMECORE | Status) with HOMECORE active, a left sub-nav for the nine
// HOMECORE sections, and a hash router. One shared WebSocket feeds a bus
// that every panel subscribes to (no per-panel sockets, no polling).
