Side B implements a real DSL redesign (explanation-first vote syntax, block-prefix parsing logic) with corresponding parser changes, error handling, and updates across many test fixtures, docs, and browser tests, representing substantial lasting design work. Side A is a small, focused bugfix (skip pinned Reddit posts) with a test, which is valuable but far narrower in scope and impact than B's language-level change.
