Test fixture: older post (no author)

This is a test fixture post used by the E4-T1 Playwright suite. It exists to prove:

1. Reverse-chronological order — this post (2026-05-01) must appear AFTER “Five retention leaks hiding in your Discord” (2026-06-12) on the blog index.
2. Optional author — no author frontmatter field; the meta line must not render a dangling ·.
