It works!

If you can see this post at /blogs/testing-refactor, your unified routing system is fully operational.

This post proves that:

1. The posts collection is correctly configured in content.config.ts.
2. The Universal Route [category]/[slug].astro is successfully catching the request.
3. The category frontmatter is driving the URL structure.

Go ahead and try changing the category to coding or projects in the frontmatter above and save it—watch the URL change automatically to /coding/testing-refactor.
