  // In production the SPA is served same-origin behind Caddy, which proxies /api and
  // /nats to the cluster; those relative paths do not exist on the bare dev server, so
  // `pnpm dev` must be pointed at a real cluster node with VITE_BUS_HTTP / VITE_BUS_WS
  // (busService.ts uses them as overrides of the same-origin defaults). Example:
  //   VITE_BUS_HTTP=https://<node>:8470 VITE_BUS_WS=wss://<node>:8480 pnpm dev
  // The dev server runs on 5174 (5173 is reserved for an unrelated local app). Add the
  // dev origin (http://localhost:5174) to the node's --cors-origins allowlist. strictPort
  // is left off, so Vite falls back to the next free port if 5174 is busy.
