- Add blog content module (posts.ts): 4 platform-focused articles (deploy, managed databases, custom domain + SSL, replicas & cost) in fa/en with tag, date, reading time, excerpt and structured body. - Self-contained gradient cover art (BlogCover) — no external images, themed per topic with the brand cloud motif. - Landing blog section now shows the 3 latest posts with covers, linking to article pages; "view all" links to /blog. - Dedicated /blog list page and /blog/[slug] article page over the shared cloud-sky shell (BlogShell), with a not-found state. - Remove the now-redundant "Learn" header nav item (blog covers getting started) and drop its orphan section anchor. - i18n: blog minRead/notFound/backToBlog strings.
