Remove render_to_sx from public API: enforce sx_call for all service code
Replace ~250 render_to_sx calls across all services with sync sx_call,
converting many async functions to sync where no other awaits remained.
Make render_to_sx/render_to_sx_with_env private (_render_to_sx).
Add (post-header-ctx) IO primitive and shared post/post-admin defmacros.
Convert built-in post/post-admin layouts from Python to register_sx_layout
with .sx defcomps. Remove dead post_admin_mobile_nav_sx.

Cart identity

Cart items are keyed by user_id (logged in) or session_id (anonymous). On login, anonymous cart items are adopted to the user's account.

Cross-domain communication

  • services.calendar.* — claim/confirm entries for orders, adopt on login
  • services.market.* — marketplace queries for page-scoped carts
  • services.blog.* — post lookup for page context

Fragments served

  • cart-mini — cart icon + badge count
  • account-nav-item — orders link for account nav

Checkout flow

  1. User clicks "Checkout"
  2. create_order_from_cart() creates Order + OrderItems
  3. services.calendar.claim_entries_for_order() marks entries as "ordered"
  4. Emits Create / rose:Order activity
  5. SumUp hosted checkout created, user redirected
  6. SumUp webhook / return page triggers check_sumup_status()
  7. If PAID: services.calendar.confirm_entries_for_order(), emits rose:OrderPaid
