A adds lasting product capability: EntityData gains image_url/link_url with real Reddit preview/link parsing, a dedicated render::reddit path for post cards/thumbnails, CSS, and a fixture-backed test. B mainly consolidates already-working web ingest/check/redact onto POST /ui by deleting web_post.rs and rewriting callers/tests—valuable cleanup, but largely relocation of existing behavior rather than new design substance.
