openai/gpt-5.3-chat → B (3:1)

Side B replaces two manually enumerated Kaocha suites with a single auto-discovered suite using `:ns-patterns ["^test\\..+"]`, ensuring new tests run without config changes and preventing silent omissions. Side A mainly removes a wrapping `section.vote-compare-shell` and adds CSS styling for ranking lists, which is largely presentational and less impactful on long-term correctness or maintenance.
