Two Column Layout with Featured Post and Additional Posts

This two column layout utilizes Tailwind's grid system to create a featured post on the left and additional posts on the right. The left column spans the full width on mobile and splits into side-by-side columns on larger screens. The featured post includes author info and a link, while the additional posts on the right show author avatar, title, excerpt, and link. Styling using Tailwind utilities provides the desired visual treatment.
