 1. ~~**Order management admin**~~ — ✅ Complete (02cdc81). Admin UI at `/admin/orders` with status filter tabs, streamed order table, and detail view showing items, totals, and shipping address.
 2. ~~**Orders & fulfilment**~~ — ✅ Complete. Submit paid orders to Printify, track fulfilment status (submitted → processing → shipped → delivered), webhook-driven status updates with polling fallback, admin UI with submit/refresh actions.
 3. ~~**Transactional emails**~~ — ✅ Complete. Plain text order confirmation (on payment via Stripe webhook) and shipping notification (on dispatch via Printify webhook + polling fallback). OrderNotifier module, 10 tests.
-4. **Default content pages** — Static pages for terms of service, delivery & refunds policy, and privacy policy. Needed for legal compliance before taking real orders. Can be simple markdown-rendered pages initially, upgraded to editable via page editor later.
+4. ~~**Default content pages**~~ — ✅ Complete (5a43cfc). Generic `ShopLive.Content` LiveView handles about + 3 policy pages (delivery, privacy, terms) via `live_action`. Rich text with list blocks, footer links updated, theme editor preview. 10 tests (575 total).

+### DRY Refactor
+**Status:** Planned
+
+Codebase analysis identified ~380 lines of duplication across LiveViews, templates, and the theme editor. Top priorities: extract `ThemeHook` for shared mount logic, extract `<.shop_layout>` wrapper component, consolidate preview assigns. Also: split `shop_components.ex` (4,400 lines) into focused modules.
