22 Years Later: How I Finally Migrated My WordPress Blog to Astro with AI as My Coding Intern

Last Thursday, my WordPress blog went down again. Nothing unusual—it always comes back by itself—but there I was, staring at another reminder of the aging VPS, the security concerns, and the maintenance overhead I'd been avoiding for years.
