Create two minimalist, professional UI cards for a B2B software platform. Each card should have a clean, corporate design with a white background, rounded corners, and subtle shadow effects for depth. No photos should be used; rely on graphic elements only. JAM QUADRANT Card: This card should represent a product focused on competitive positioning, similar to a Gartner Magic Quadrant. Display the title 'JAM QUADRANT' in bold black text at the top center. Include a simple quadrant icon or grid graphic with four quadrants, using light gray tones. Add small dots or markers to represent companies within the quadrants, maintaining a monochromatic color scheme. Beneath the graphic, add placeholder text in dark gray to briefly describe the product. Place a small, outlined button labeled 'Credits: 3' on the right side, with a black outline and black text on a white background. Add a subtle yellow accent (#edea58) in minimal touches to highlight important elements. JAM METRICS Card: This card should represent a product focused on numerical and graphical analysis. Display the title 'JAM METRICS' in bold black text at the top center. Include minimalistic icons for charts (such as bar charts or scatter plots) below the title, using dark gray or light gray colors. Add placeholder text in dark gray to describe the product briefly. Include a small black button with white text, labeled 'Purchase,' placed on the right side. Add small yellow accent elements (#edea58) to subtly emphasize specific aspects. Both cards should look balanced, with ample whitespace and a sophisticated visual style suitable for a business intelligence platform.
