+### P21 菜单系统重构 — 主菜单 + 暂停菜单 + 设置 + 游戏内顶栏 ✅ 已完成 2026-06-10
+
+目标：按照行业标准（Detroit / Dark Pictures / Telltale）重新整理四个菜单系统的设计和交互。
+
+**现状 vs 业界差距：**
+
+| 菜单 | 现状 | 业界标准 |
+|------|------|---------|
+| 主菜单 | 两行横排 7 个按钮，LangSwitch 悬浮 | 竖排单列 4-5 项，语言在设置里，背景视频可见 |
+| 游戏内顶栏 | 左侧 LangSwitch + PlaybackBar，右侧 3 个按钮 = 共 5 项 | 几乎无 HUD，仅角落菜单图标 |
+| ESC 行为 | 直接打开 SaveLoadMenu | 打开暂停菜单（存档是子项） |
+| 设置面板 | AccessibilitySettings 独立面板 | 设置中分类展示，**语言在设置里** |
+
+**四个菜单系统重新规划：**
+
+**1. 主菜单（MainMenu.vue 重设计）**
+
+```
+(menuVideo 循环播放作为背景，半透 overlay)
+
+              [ 新游戏 ]               ← 竖排，最大
+              [ 继续 ]                 ← 可选
+
+         章节选择  ·  成就  ·  画廊  ·  设置   ← 底部小字装饰行
+```
+
+- 改为竖排单列，视觉层次分明
+- LangSwitch 移除，语言挪到设置面板
+- 半透明 overlay，menuVideo 背景可透
+
+**2. 游戏内顶栏（App.vue 精简）**
+
+```
+左：跳过(条件) · 倍速(条���)           右：全屏 · [ ≡ ]
+```
+
+- LangSwitch 移除
+- 设置按钮移除，统一在 ≡ 暂停菜单内
+- ≡ 按钮基于现有的"菜单"/"设置"入口替代
+
+**3. ESC 暂停菜单（新建 `PauseMenu.vue`）**
+
+```
+(当前视频暂停，半透明遮罩覆盖)
+
+              [ 继续游戏 ]              ← 或按 Space/Esc
+              [ 存档 / 读档 ]
+              [ 设置 ]
+              [ 返回主菜单 ]
+```
+
+- 不再直接打开 SaveLoadMenu
+- 第一个 Esc 打开暂停菜单，再按 Esc 继续
+
+**4. 设置面板（AccessibilitySettings.vue 升级）**
+
+```
+             语言：中文 ▼  English       ← 顶部新增
+
+             字幕字号：20 ▼
+             字幕背景透明：0 ▼
+             QTE 时限放宽：关/开
+             QTE 按键简化：关/开
+             防误触延迟：开/关
+             可暂停：开/关
+```
+
+- 语言选择下拉移到这里
+
+**实现清单：**
+
+- [x] `src/components/PauseMenu.vue` — **新增** — ESC 暂停菜单：继续/存档/设置/返回主菜单 + 按 Esc 继续提示
+- [x] `src/components/MainMenu.vue` — 竖排单列设计：开始最大、继续次之、底部装饰行、移除 LangSwitch
+- [x] `src/components/AccessibilitySettings.vue` — 顶部新增语言选择下拉（中文/English）
+- [x] `src/App.vue` — 顶栏精简到跳过/倍速/全屏/≡；ESC 打开 PauseMenu 替代直接开 SaveLoadMenu；移除 LangSwitch
+- [x] `src/locales/zh.json` + `en.json` — 新增 8 个 PauseMenu 专用翻译 key
+- [x] 验证：TypeScript + Vite build 通过
