B adds substantial new functionality (image/link extraction, dedicated render module, thumbnail rendering in lists, and full-size images in post detail) with a new module, CSS, and fixture-backed tests, providing broader lasting value despite the terse commit message. A is a small, focused, well-tested bugfix (skipping pinned posts) that is correct and clean but narrower in scope and impact than B's feature work.

council reasoning
B adds lasting product surface: EntityData image/link fields, Reddit image/URL parsing, a new render module with post cards/thumb rows, and HTML/CSS integration plus a fixture test. A is a correct, tested filter to skip stickied/pinned listing children, but it is a narrow import tweak versus B’s end-to-end Reddit presentation path.
Side B adds substantial new functionality across the data model and UI: it extends `EntityData` with `image_url` and `link_url`, extracts those fields from Reddit payloads, introduces reusable Reddit-specific rendering for post cards and thumbnail rows, wires it into existing HTML, and includes fixture-backed tests. Side A is a targeted correctness fix that skips stickied/pinned subreddit posts during import with a focused helper and regression test, but its scope and impact are much narrower than the end-to-end feature added in Side B.
