Side A introduces a substantial new UI architecture: a unified POST /ui endpoint, the HtmlUiAction command model with JSON template parsing and form-hole substitution, reusable web action handlers, and integration into routing and forum rendering. Side B is a valuable correctness fix that consistently enforces vote-ratio bounds (both sides >=1 and <=100) across the parser, UI handler, reducer, and tests, but it is a comparatively localized validation change rather than a broad, reusable capability.
