Side A introduces a new generalized HTML UI action system with a single `/ui` endpoint, reusable `run_*` handlers extracted from existing web post logic, and a JSON form-template mechanism (`$form` substitution) backed by tests. Side B adds a substantial Reddit background fetcher with OAuth, rate limiting, and parsing, but much of it is infrastructure tied to an external integration, whereas Side A delivers a reusable architectural improvement that consolidates browser UI handling and reduces duplication across the project.
