The trends grid lost its disk chart; add it back as a 6th card plotting root-filesystem % over time, alongside CPU/Memory/Network/Load/Swap. The 'disk' history series and metric-detail entry already existed, so the expand-to-detail flow works unchanged.

// Admin → System — orchestrator + index view.
|
||
//
|
||
// One AdminSystem instance per page mount. Reads the URL path on init and
|
||
// dispatches to one of four sub-views:
|
||
//
|
||
// /admin/config/system → index (gauges + trends + per-app table)
|
||
// /admin/config/system/metric/<key> → single-metric deep-dive page
|
||
// /admin/config/system/app/<name> → per-container app deep-dive
|
||
// /admin/config/system/storage → Docker disk breakdown
|
||
//
|
||
// Sub-views are separate page renderers (system-metric-page.js etc.) that
|
||
// each own their own DOM + lifecycle inside #config-section. We mount one
|
||
// at a time; switching means tearing down the active renderer and starting
|
||
// a fresh one. The SPA re-runs handleAdmin() on every navigation, which
|
||
// re-runs ConfigManager.renderConfig('system') → AdminSystem.init, so the
|
||
// dispatch happens organically with the router.
|
||
//
|
||
// Live (1 Hz, via LiveSystem SSE) data flows directly to whichever sub-view
|
||
// is mounted. The index view ticks gauges in place; the metric page splices
|
||
// the live value into its chart's tail.
