 Full spec in [`SKILL.md`](./SKILL.md).
 
+## Presenter mode
+
+Both templates ship with the same presenter runtime. Open a deck and press the bottom-right `P` to enter presenter view; the browser opens a clean audience window at the same time. Core features run entirely inside the local HTML and browser—no live-caption service, cloud relay, phone remote, or AI coaching service is required.
+
+### What the speaker sees
+
+- **Current and next slides**: stacked vertically and always kept at `16:9`; small windows scale the whole slide without cropping or reflowing its text
+- **Grid navigation**: replace the preview area with an inline overview, choose a slide, then return immediately to the two previews while the audience follows
+- **Structured notes**: title, purpose, talking points, and transition are required; interaction, delivery, advance cue, fallback, and pronunciation appear only when supplied by the outline
+- **Progress and health**: current / total slide count, completion percentage, plus audience states for connecting, synced, unsynced, frozen, disconnected, or popup blocked
+
+### Timing, rehearsal, and auto advance
+
+- The footer separates elapsed, current-slide, and remaining / overtime values, with explicit “Start timer / Resume timer / Reset timer” controls
+- Rehearsal mode records actual time per slide and a local session summary; it does not grade the speaker with AI
+- Auto advance is off by default and only runs when the outline provides per-slide seconds or the user enables a global interval
+- Auto advance pauses while the grid, settings, or annotation tool is open, when the page is hidden, or when the audience is paused or out of sync
+
+### Live tools and recovery
+
+- Laser pointer, circle annotation, and clear actions sync to the audience window
+- Black screen, white screen, or freeze the audience; unfreezing catches it up to the presenter's current slide
+- Closing the audience window or losing its heartbeat produces a visible “Disconnected” state; “Reopen audience” is always available
+- Exiting presenter mode closes the audience window when allowed, or leaves a clear “Presentation ended” fallback
+- Preflight checks cover popups, fullscreen, fonts, images / video, and `16:9` previews, while reminding the speaker to verify HDMI adapters and projectors manually
+
+Common shortcuts: `← / →` navigate, `Home / End` jump to first or last, `G` opens the grid, `L` laser, `C` circle, `B / W` black or white screen, `F` freezes the audience, and `?` opens the full shortcut list.
+
+Ask an agent to prepare presenter mode with:
+
+```text
+Use this outline to add a purpose, talking points, transition, and planned duration to every slide. Do not invent interaction or live details that were not provided, then run the presenter-mode validator.
+```
+
+See [`references/presenter-mode.md`](./references/presenter-mode.md) for the full notes contract and runtime behavior. Validate with:
+
+```bash
+node scripts/validate-presenter-mode.mjs path/to/index.html
+node scripts/validate-presenter-mode.mjs path/to/index.html --target-minutes 30

+- 排练模式记录每页实际时长和整场汇总,数据保存在本地浏览器,不会做 AI 评分
+- 自动翻页默认关闭；只有大纲明确给出页面停留秒数,或用户在设置中开启全局间隔时才启用
+- 打开宫格、设置、圈选工具,页面隐藏,或观众屏暂停 / 失去同步时,自动翻页会暂停
+
+### 现场工具与故障恢复
