Single column

The pane fills the host container's full width — typical for a standalone scorecard or a focused dashboard. Tests the wide-mode rendering: 120px score ring, full-text column headers, two-layer embedded section (wash + frame).

Two columns

Same pane, embedded twice in a two-column grid — typical for a multi-account or multi-region portal. Each pane sees its own container width and adapts independently. At ≥460px-per-column the wide layout still applies; the grid collapses to one column on narrow viewports.
