- Backend GET /api/system-monitor/stats: one snapshot — CPU overall + per-core
(two /proc/stat samples), memory + swap (/proc/meminfo), disks (df), load,
uptime, top-20 processes (ps). Owner-only via the account gate.
- Frontend /system-monitor screen: polls every 2s; CPU/Memory/Disks cards with
bars + per-core mini-bars, top-processes table. Nav dock "Monitor" item.
- Register /music and /system-monitor in usePageTitle RULES so the browser tab
and editable header title update on those routes (/music was missing too).
