The shared term cover helper read aksrt_cover_url/cover_url term meta, keys this theme never writes, so 分类图文卡片 dropped every card and 分类聚合卡片 always rendered an empty cover box. Resolve covers the way the rest of the theme does (aksrt_category_cover_id → latest thumbnailed post in the term), and let the aggregation card fall back to the theme placeholder while term cards stay hidden without a real cover.
