Side B delivers substantial functional improvements to the vote-compare feature: it adds a reusable chromeless layout, updates the POST success flow to morph a preview card and refreshed history, normalizes and sorts vote ratios for display, adjusts UI/CSS, and adds unit/browser test coverage for the new behavior. Side A is a useful maintenance improvement that replaces manually enumerated Kaocha suites with automatic test namespace discovery, reducing future configuration work, but it is a much narrower infrastructure change.
