Core Content Panel
This main panel expands and contracts with the viewport. On desktop it stays beside the sidebar; on mobile it shifts below the header and above the sidebar for better reading flow.
The boxed sections use % and clamp() units so text and spacing remain legible in portrait and landscape modes.

Thanks to CSS Grid and responsive media queries, the layout adapts at 980px and 570px breakpoints. The perimeter size and padding adjust for smaller screens.
