// Dashboard view model (todo §10): the gated "/dashboard" app home. By default a short instructional
// starter — what the dashboard is and how to replace it by exporting a `dashboard` handler from a
// plugin (views/index.ejs holds the prose). A plugin owns the real one (PluginManifest.dashboard);
// this placeholder renders until then. Pure: `nav` is the one global menu (ctx.chrome.nav), built
// once per request by the host, so the dashboard shows the exact same menu as every other page.
