+   * 资源总览（main 态）必须为**每个非空栏目**挂载真实卡片本体。
+   *
+   * 回归背景：卡片预览 Hook 的 `resources` 入参同时决定 `identityByResourceId`，而
+   * `renderResourceBookCard` 在身份缺失时直接不挂载卡片。曾为缩小热预取范围把该入参
+   * 收窄成「当前分页栏目」，结果总览里除当前栏目外只剩栏目标题栏加空的层叠占位。
+   *
+   * 本用例自带 manifest（不改上面共用 fixture），并把 `category` 显式写死，
+   * 让 `audio` / `document` / `character` / `unclassified` / `version` 五个栏目同时非空。
+   * `audio` 刻意保持 `idle`（音频不接受可见性预取），用来证明卡片挂载不依赖预览是否已就绪。
