Two levels: the Overview grid is every system at a glance — click a tile to jump to and open its section. Each category below is a drill-down you expand or collapse (click the header, or use Expand/Collapse all). All-green categories (Snapshots, Network) start collapsed — on a fully-healthy day every section collapses and the console is the masthead + overview. Verdict lamp reads worst diagnostic state only — the fstrim fail and the 3 CVEs are actionable/updates, so the box still reads HEALTHY.
