I've updated the design to match the screenshot exactly, ensuring:

1. Each section takes up the full width of the content area
2. Removed the Card components and used direct div styling for better width control
3. Matched the exact padding and spacing from the screenshot
4. Used the correct colors from the Figma context
5. Implemented the avatar system with letters instead of images
6. Matched the typography and text hierarchy

The layout now properly extends to the full width of the container while maintaining the clean, minimal design from the screenshot. Would you like me to add the remaining sections (Recent Files and Calendar Events) with the same full-width styling?

Key changes made to ensure full width:

1. Removed the SidebarInset wrapper as it was constraining the width
2. Added proper padding with px-8 to match the screenshot
3. Used w-full on all sections to ensure they take up the entire width
4. Simplified the structure to remove any unnecessary wrapper elements
5. Added the missing Recent Files and Calendar Events sections
6. Ensured consistent spacing with space-y-6 between sections
7. Used semantic <section> tags for better HTML structure

The dashboard should now take up the full width of the page while maintaining the clean design from the screenshot.
