openai/gpt-chat-latest → A (9:1)

Side A introduces substantive functionality and infrastructure: typed form-template substitution for i32 fields with tests, a new `next` navigation flow after recording votes, routing/hooks for a voting UI, and supporting client-side behavior and dependencies. Side B only removes a redundant zero-ratio guard from `apply_vote` and updates the corresponding test expectations, which is a small cleanup compared with A's broader, lasting feature and correctness improvements.
