+# ReelShort 客户端深色视觉改造
+
+## 目标
+
+- 深色设为默认且唯一主题，页面、卡片、浮层、播放器和底部导航保持一致。
+- 色板收敛到 `AppColors`，主题组件配置收敛到 `AppTheme`。
+- 保持现有布局、信息结构、路由、业务逻辑和文案不变。
+
+## 结果
+
+- 背景 `#0B1020`、卡片 `#151B2E`、浮层 `#1C2436`、分割线白色 6%。
+- 主文字白色 92%、次文字 64%、禁用 38%。
+- 主色 `#FF6B2C`，辅助链接色 `#22D3EE`。
+- 卡片 12、按钮/输入框 10、标签 6，阴影关闭，组件使用分割线分层。
+- 页面级透明、遮罩、阴影、媒体底、玻璃面和渐变全部映射到 AppColors 语义 token。
+- 系统栏统一浅色图标，AppBar 与底部导航使用深色表面。
+
+## 验证
+
+- 主题 token、对比度、系统栏、圆角与关键页 smoke 测试。
+- `dart analyze lib test`
+- `flutter test --no-pub`
+- `flutter build apk --debug`
+
+## 约束
+
+- 不提交 `pubspec.lock` 漂移。
+- 不启停服务、不操作真机。

+## 2026-10-22 ReelShort 客户端深色视觉改造
+
+- 分支：`feature/dark-theme-client`
+- 基线：开发前已有约 43 个未提交视觉文件，本次在原改动上继续收敛，未推倒重来。
+- 计划：`docs/plans/2026-10-22-dark-theme-client.md`
+
+### 颜色与主题
+
+- `AppTheme.dark()` 成为默认且唯一主题，系统状态栏/导航栏图标统一浅色。
+- 色板统一为背景 `#0B1020`、卡片 `#151B2E`、浮层 `#1C2436`、
+  divider `#0FFFFFFF`、主色 `#FF6B2C`、辅助链接色 `#22D3EE`。
+- 主/次/禁用文字分别使用白色 92% / 64% / 38%。
+- 卡片/按钮/输入框/标签圆角统一为 12/10/10/6，卡片阴影关闭。
+- 页面和组件内的 `Colors.*`、`Color(0x...)` 已全部映射到 `AppColors`
+  语义 token；剩余原始色值只在 `app_colors.dart` 中定义。
+- 导航、玻璃面板、播放器遮罩、加载轨道、渐变、边框和阴影均改为深色语义。
+- 修正全局输入装饰 padding 导致账户性别下拉溢出，保持原布局宽度。

+## 2026-10-22 客户端底部导航改为首页/推荐/追剧/我的
+
+- 分支：`feature/client-bottom-nav-4tabs`
+- 基线：`develop` / `origin/develop` = `ec3cb8f`
+- 计划：`docs/plans/2026-10-22-client-bottom-nav-4tabs.md`
+- 实现提交：`91e869d feat(nav): 底部导航改为首页推荐追剧我的`
+
+### 问题
+
+根导航仍为首页/剧场/创作/我的，底栏选中态使用品牌橙。追剧若通过新路由打开，
+会叠加第二层底栏并产生返回栈，不符合参考图和单根导航交互。
+
+### 改动
+
+- 新增 `AppRootTab` 统一四个 tab 的顺序、key、图标和 l10n 标签。
+- `AppBottomNav` 改为纯黑底、白色选中、`#8A8A8E` 未选中，图标 24、文字 11，
+  保留 SafeArea 与轻震动。
+- 首页 `IndexedStack` 第三槽直接使用 `FavoritesContent`，不再 push 收藏路由。
+  追剧保留顶部标题区、隐藏返回按钮，只有一个根底栏，不创建嵌套 Scaffold。
+- `FavoritesPage` 保留独立 Scaffold 和返回行为，继续供“我的”入口使用。
+- 推荐、追剧、我的三个根页面统一调用 `HomeLogic.select` 切换，不进入返回栈。
+- 创作页保留，`mine-creator-center` 入口保留；创作不再出现在根底栏。
+- 中文使用“追剧”，英文使用 `Home / Recommend / Following / My`，
+  印尼语使用 `Beranda / Rekomendasi / Daftar Tonton / Saya`。
+- `FavoritesContent` 内置顶部 SafeArea，避免嵌入首页后被状态栏遮挡。
+

+
+导航测试覆盖：四个 tab 数量与顺序、纯白/灰色状态、点击追剧进入
+`FavoritesContent`、仅一个 `AppBottomNav`、追剧内部无嵌套 Scaffold、
+`Navigator.canPop == false`、创作不再出现在底栏且我的入口保留。
+
+解读：静态分析零告警，644 项测试全部通过；追剧与首页/推荐/我的均在同一根页面
+内切换，无叠加导航或返回栈。`pubspec.lock` 未提交，未启动或停止服务，未操作真机。
+
+## 2026-10-22 根导航布局规格对齐

+- 分支：`feature/client-bottom-nav-layout`
+- 基线：`develop` / `origin/develop` = `667fdc5`
+- 实现提交：`81787dc style(nav): 对齐四 Tab 底栏布局规格`
+
+### 改动
+
+- 新增 `AppRootBottomNav` 作为首页、推荐、追剧、我的唯一根导航入口，
+  三个 Shell 页面不再各自拼装 item。
+- 四列使用 `Expanded` 等分，图标在上、文字在下，间距 4。
+- 内容高度 56，另由 `SafeArea` 增加底部安全区；图标 26、文字 11、
+  `letterSpacing = 0`，选中 `w600`、未选中 `w400`。
+- 背景纯黑，取消顶部边框；选中 `#FFFFFF`，未选中 `#8E8E93`。
+- 首页、推荐、书签、人像继续使用各自的选中实心/未选中描边图标。
