openai/gpt-5.2-chat → B (4:1)

Side B fixes substantive behavior in the /vote flow: it passes WEB_BROWSER_AGENT as an out-of-band delegate instead of injecting it into the DSL text, removes an incorrect fallback when the sibling pool < 2 (returning None instead of voting over all items), drops the pointless "swap sides" button, and consistently renames and rewires the route from /vote/compare to /vote across handlers, links, and tests. Side A is a small UI/CSS tweak moving the view counter into the nav to avoid overlap, which is minor compared to B’s functional and routing corrections.
