Generate a visual KPI report card image at 1200x628 pixels. Use the generate_image tool with these layers:
1. Background: solid-color layer with [background color]
2. Headline metric: text layer with [primary metric value] in large bold text
3. Metric label: text layer with [metric name] below the headline
4. Secondary stats: text layers for [stat 1 label]: [stat 1 value], [stat 2 label]: [stat 2 value], [stat 3 label]: [stat 3 value]
5. Branding: text layer with [company/report name] and date
