All three services now fetch page data via (service ...) IO primitives in .sx defpages instead of Python middleman functions. - Account: newsletters-data → AccountPageService.newsletters_data - Federation: 8 page helpers → FederationPageService methods (timeline, compose, search, following, followers, notifications) - Cart: 4 page helpers → CartPageService methods (overview, page-cart, admin, payments) - Serializers moved to service modules, thin delegates kept for routes - ~520 lines of Python page helpers removed Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
