 ### 模板系统
 
 5 个模板（news、knowledge、opinion、marketing、github-trending），每个在 `packages/templates/src/<name>/index.tsx` 中有对应的场景组件。共享基础组件位于 `packages/templates/src/base/`。`Root.tsx` 按以下规则路由：
-- `sceneType === "cover"` → 内置 `CoverScene`
+- `sceneType === "cover"` → 内置 `CoverScene`（`github-trending` 的 cover 接收 `coverTags`/`trendSummary`，在首屏渲染主题标签行 + 一句话趋势句）
 - `sceneType === "outro"` → 内置 `OutroScene`
-- `sceneType === "summary"` 且 `template === "github-trending"` → `GithubTrendingSummaryScene`（仅此模板有 summary 场景）
 - 其他 content 类型 → `SCENE_MAP[template]` 对应模板组件
 
 `github-trending` 是当前唯一带 `isPortrait` 分支的模板，竖屏布局采用 flex column（头部取自然高度，内容 flex 填充），横屏保持绝对定位。`Section` 子组件通过 `size: "default" | "large"` 区分横竖屏字号档位，并用 `-webkit-line-clamp` 做安全截断（body 用 `flex: "0 0 auto"` 防止 shrink 导致的单行底部裁剪）。

-- Do not create overview, summary, or trend-overview scenes — the pipeline injects a dedicated summary scene separately. Each repo scene MUST focus on its own repo.
+- Do not create overview, summary, or trend-overview SCENES. The opening title screen (cover) is built by the pipeline; it does not need a scene. Instead, convey the day's overall theme via the two top-level cover metadata fields below. Each repo scene MUST focus on its own repo.
 - The output for this template relies on structured metadata embedded in the input. Treat that metadata as authoritative — DO NOT paraphrase or invent values.
 
+COVER METADATA (github-trending only — emit these two TOP-LEVEL fields alongside title/summary; omit them for every other template):
+- coverTags: ≤5 short theme tags (2-6 Chinese chars, or a short English term). Each tag names the main technical AREA or THEME a selected repo belongs to — e.g. "代码智能", "时序模型", "视频编辑", "情报看板", "生成式AI", "AI Agent", "Rust 运行时". NOT programming languages and NOT repo names. Prefer one tag per selected repo; if two repos share a theme, merge them and pick a distinct area so the set still spans up to 5 areas. Plain CJK/ASCII only — no emoji, no decorative symbols.
+- trendSummary: one short sentence (≤30 chars) synthesizing the overall trend across today's repos — what theme is hot or emerging. Must read as an editorial insight, NOT a restatement of the tags or a generic filler. Example: "AI Agent 与代码智能工具持续升温". Plain CJK/ASCII only.

 displayText: the repo's fullName (e.g. "facebook/react"). Nothing else.
