Single column

Full-width pane — typical for an oncall dashboard. Three counters across the top (in alarm / OK / insufficient data), then per-category sections with sparklines on the alarm rows and an OK roll-up at the foot of each section.

Two columns

Same pane embedded twice — multi-environment side-by-side. Each pane reads its own container width and adapts independently.
