Side A adds the core Reddit integration: a background fetch broker, OAuth support, request deduplication and rate limiting, JSON parsing into project entities, wiring into application state, and triggering fetches from browsing and path creation. Side B is a targeted refinement that improves the existing integration by requiring OAuth when configured, refreshing tokens after 401/403 responses, and producing clearer error messages for Reddit's block pages, but it builds on the infrastructure introduced in Side A.
