Utilize the dark theme with the custom colors (#7f40dd for headers and #f5db5b for key metrics) to create a visually striking contrast. Ensure a 4.5:1 ratio for accessibility on all text elements.

Implement a 12-column grid layout for a 16:9 ratio, positioning KPIs at the top row for immediate visibility. Place the geographic map in the first column, the gauge in the second column, and use remaining space for charts and tables.

Use a single font family, such as Inter or Segoe UI, with a size hierarchy: Dashboard title at 28px bold, section headers at 20px semibold, KPI labels at 16px medium, and body text at 14px regular for clarity.

Select chart types that best represent data context: use a geographic map for incident locations, gauge charts for latency targets, and heatmaps for error distribution. Limit colors per chart to ensure clarity and add tooltips for data context.

Create a clear visual hierarchy with the most critical metrics in larger, bolder fonts. Use whitespace effectively to separate sections and apply conditional formatting to highlight areas of concern, e.g., red for increasing latency.

Implement hover states for interactive elements to enhance user experience. Use loading skeletons during data refresh and provide visual feedback on filter selections to keep users informed.
