Test Article
This is a test article

Module 4 built and committed. Dev server's already running at localhost:5180. Here's what's there — walk through it and tell me what breaks:
Articles (sidebar) — empty list right now, "New article" button top-right
Click New article: title, slug (auto-fills from title, editable), dek, and a real Tiptap editor (Bold/Italic/H2/H3/lists/quote/link)
Right sidebar: language, category, tags (click to toggle), featured image URL, meta title/description, and a live SEO checklist — the hard checks (title, meta title/description, category) actually gate the Publish button, not just decoration
Save works at any time regardless of checklist state; Submit for review appears once it's a draft; Publish only appears at all because you're Admin — worth testing what an Author account sees (should have no Publish button, and if you try to force it another way, the database trigger from Module 2 should still block it)
Try the "Translation of" dropdown on a second new article once you have one saved — it should let you link the two into the same
translation_group_id
