 * monitor.css — the Monitor page.

 * Port of Foundation/MachineStatusView/Sources/MachineStatusView/{MonitorDashboard,

 * there is room (Load, Processor, Memory, Disks | Receive+Transmit, Network,
 * Graphics), one column below 760pt.
 *
 * Each card "answers one question with one large number", so the metric line is
 * always rxMetricXL (32pt semibold, tabular) with a 13pt unit beside it.
