openai/gpt-chat-latest → B (8:1)

Side B replaces a large, unreliable autocomplete transition-graph system with a much simpler URL parser that extracts subreddit names, redirects directly to the ranking page, removes obsolete parser infrastructure, updates the UI flow, and adds focused tests for the new behavior. Side A is primarily visual polish and accessibility improvements in CSS (focus-visible states, spacing, styling, and vote-compare layout), which improve usability but do not change the project's core behavior as substantially.
