Side B implements a substantial, self-contained new feature: an async Reddit fetch broker with OAuth handling, rate-limit backoff, caching, JSON parsing for subreddits/posts, and tests, wired cleanly into AppState and the browse handler. Side A is a large, mostly mechanical DSL syntax reshuffle (trailing to leading explanation blocks) touching many tests/fixtures/docs, which is a real but narrower, more churn-heavy change with less net new capability despite its size.
