Side B adds durable functionality and structure to the vote-compare flow: it introduces a reusable chromeless fullscreen layout, updates successful vote submissions to morph in the new post preview, normalizes and sorts edge-history ratios relative to the displayed left/right pair, and adds unit/browser test coverage for the new behavior. Side A makes a useful correctness fix by using display paths in vote URLs and strengthens testing with an exhaustive 45-pair ranking assertion, but its production code changes are comparatively small and primarily supported by expanded tests.
