+# 收藏卡片简介
+
+## 目标
+
+- 收藏卡片在标题/标签下方显示后端 `synopsis`，最多 2 行并省略溢出。
+- 空白简介不创建文本节点、不占高度，不显示 `null/undefined`。
+- 保持封面 80x106 和现有卡片高度，不引入布局溢出。
+
+## 实现
+
+1. `_FavoriteCard` 对 synopsis 做 trim 后条件渲染。
+2. 简介使用 `Flexible` 占据标题、标签与底部统计之间的剩余空间，
+   `maxLines: 2`、`TextOverflow.ellipsis`、次要文案色和字号。
+3. 无简介时继续使用原 Spacer，保持原布局。
+4. widget 测试覆盖有简介、空简介和卡片高度稳定性。
+
+## 约束
+
+- 不改接口、后端、收藏分页。
+- 不新增依赖，不提交现有 `pubspec.lock`，不启停服务、不操作真机。
