The blog showed "Posts coming soon" live: the app reads process.cwd()/content
= web/content at runtime (that's where the old orphan lived and rendered), but
the 5 articles were committed to REPO-ROOT content/articles — which the
deployed app never reads. Moved them to web/content/articles (verified
getAllPosts finds all 5 from cwd=web) and deleted the orphan file
web/content/blog/line-movement-guide.mdx (the route already 301s). Test paths
updated to web/content/articles.
