// components/dashboard/index.js — the landing Dashboard as a feature module.
//
// dashboard.js exposes bare global functions (loadInstalledApps,
// loadDashboardData live in dashboard.js / data-loader.js, both eager core
// scripts) — there is no controller class to lazy-load, so scripts is empty.
// system-loader's 'dashboard' component already ran initializeData()/
// loadSystemInfo()/setupEventListeners() once at boot; mount() only does the
// per-navigation refresh (mirrors the old handleDashboard + the navigate()
// data-reload special-case, which has been removed from spa.js so the reload
// now fires exactly once here).
LP.features.register({
  id: 'dashboard',
  routes: ['/', '/dashboard'],

    const html = await ctx.loadFragment('/components/dashboard/html/dashboard-content.html');

    if (typeof loadInstalledApps === 'function') loadInstalledApps();

    // Repaint the stat cards / disk donut + (re)wire the 1 Hz live SSE. The
    // 100 ms cushion lets the freshly-injected DOM settle (loadSystemInfo also
    // guards on element presence). ctx.sub() cancels it if we navigate away
    // before it fires.

    // Nothing this view owns is destroyable from here: the dashboard has no
    // handler-newed controller and no system-loader singleton to tear down.
    // The pending reload timer is cancelled via the ctx.sub() above (ctx.teardown).
    // The 1 Hz LiveSystem SSE sub (attachDashboardLive) self-releases on its
    // next sample once the dashboard DOM is gone, and the 1 s update countdown
    // is a module-private interval with no exported stopper (pre-existing; it
    // self-clears on the next dashboard mount). Both are noted for the Phase 5
    // dashboard cleanup; neither is reachable here.
