Side A adds substantial new end-user functionality: Reddit-specific rendering for entity pages and ranking lists, extends `EntityData` with `image_url` and `link_url`, implements robust extraction of preview/full-image URLs while avoiding unsuitable Redgifs links, and adds a regression test fixture. Side B is primarily an architectural refactor that consolidates web posting flows into `POST /ui` and removes duplicate handlers; while useful for maintainability, it mostly reorganizes existing behavior rather than adding comparable lasting capabilities.
