This is a test to show that the article system works dynamically. By simply adding a new object to the 'posts' array in src/data/posts.ts, and giving it a new date, it appears at the top of the list.
The Process
The logic in both page.tsx and /blog/page.tsx takes the entire 'posts' array and sorts it by 'publishedDate' before rendering. This means the order in the file itself is irrelevant.
