openai/gpt-chat-latest → A (3:1)

Side A introduces a new `RouteContext` abstraction in `server/src/html/routing.rs`, re-exports it, and documents a concrete migration path toward centralized, scope-aware URL generation, creating an architectural seam that future code can build on. Side B is primarily a UI refactor that removes a wrapper element in the vote-compare template and adjusts CSS styling for ranked lists, improving presentation but not changing core behavior or architecture.
