Side A implements a genuinely new subsystem (a dedicated Reddit fetch worker with dedup, backoff, rate-limit handling, OAuth token refresh, and JSON parsing for both subreddits and posts) backed by unit tests, integrating cleanly into AppState and the browse handler. Side B adds a useful but smaller UX feature (pool-scoped vote pairing) that mostly threads an optional parameter through several existing functions and adds a UI link, which is real but far less substantial in scope and risk than A's networking/backoff/OAuth logic.
