+[PROJECT:lumaplayer] 同步远端 master
+结论: 保留本地改动并合并远端最新提交，最终 Debug 构建成功。
+文件变更: 合并源码与资源，建立本地 Git 元数据，新增 memory 记录。
+教训: 无法直接 pull 的快照应使用共同基线三方合并；认证信息不写入远端配置。
+标签: #git #sync #merge #android
+
+[PROJECT:lumaplayer] 复核 Compose 编译错误
+结论: 当前源码已包含所需作用域和导入修复，compileDebugKotlin 与 assembleDebug 均成功。
+文件变更: 无源码变更；补充本次编译验证记忆。
+教训: Kotlin 中应导入顶层符号 HomeTopBar，不使用生成的 HomeScreenKt 文件名。
+标签: #compose #kotlin #build #imports
+
+[PROJECT:lumaplayer] 直接修复 Compose 编译问题
+结论: 完成导航定义共享、Composable 作用域、ColumnScope、资源别名和 Backdrop 导入修复，assembleDebug 成功。
+文件变更: ui/LiquidGlass.kt、ui/AppBottomBar.kt、screens/SettingsScreen.kt、MainApp.kt。
+教训: 跨文件共享的顶层导航定义不能使用 private；Composable content 必须显式声明 RowScope/ColumnScope 接收者。

+结论: 移除底部导航容器及搜索按钮的白色背景，保留玻璃模糊和交互效果，assembleDebug 成功。
+文件变更: ui/AppBottomBar.kt、ui/liquidglass/LiquidBottomTabs.kt。
+教训: Backdrop 的可见底色由 onDrawSurface 控制，透明需求需同时处理外层按钮背景。

+文件变更: screens/HomeScreen.kt、screens/RecordsScreen.kt、ui/LiquidGlass.kt。
+教训: 分段切换的内容和选中态需要使用同一套动态玻璃颜色，避免固定白色造成跳变。

+结论: Emby 搜索可输入并打开详情，收藏列表可显示图片并进入详情，播放断点显示继续时间，首页 Banner 与内容区通过元数据淡入衔接，主页面和控件转场/玻璃效果已补齐。
+文件变更: MainApp.kt、data/EmbyApiModels.kt、data/EmbyRepository.kt、screens/HomeScreen.kt、screens/MediaDetailScreen.kt、screens/RecordsScreen.kt、screens/SearchScreen.kt、screens/VideoPlayerScreen.kt、ui/AppBottomBar.kt、ui/LiquidGlass.kt、ui/liquidglass/LiquidBottomTabs.kt。
+教训: Backdrop 玻璃控件必须挂在同一棵 `layerBackdrop` 来源树下；搜索选中态不能把无效索引传给固定数量的底栏动画。

+[PROJECT:lumaplayer] 修复 RenderThread 崩溃与底栏视觉
+结论: 根因是 Backdrop 捕获层内重复采样同一 backdrop 形成循环渲染；已收窄捕获范围，移除顶部玻璃底色，底栏仅保留透明轮廓、选中胶囊和搜索圆钮，模拟器启动无崩溃。
+文件变更: MainApp.kt、screens/VideoPlayerScreen.kt、ui/LiquidGlass.kt、ui/AppBottomBar.kt、ui/liquidglass/LiquidBottomTabs.kt。
+教训: `layerBackdrop` 只包背景/视频源，使用 `drawBackdrop` 的控件必须位于捕获层外。

+[PROJECT:lumaplayer] AndroidLiquidGlass 液态玻璃菜单与底栏
+结论: 语言菜单和底栏主体/搜索入口已接入 AndroidLiquidGlass-kmp 对应的 Backdrop 2.0.1 实现，展开、关闭、外部点击、语言选择和 Debug 构建均通过。
+文件变更: app/build.gradle.kts、MainApp.kt、screens/SettingsScreen.kt、ui/AppBottomBar.kt、ui/liquidglass/LiquidBottomTabs.kt，以及此前待推送的播放器、首页、搜索、收藏和数据文件。
+教训: 参考仓库没有现成菜单组件，需复用其 drawBackdrop 组件模式；来源层与玻璃消费层必须分离，外部手势层需放在菜单内容下方。

+- 中：本地目录原先没有 `.git`，不能直接 `pull`；应先获取远端历史，以共同基线做三方合并。
+- 中：合并后需编译检查跨文件 API；本次发现并修复资源别名、Backdrop 导入及底部导航 `mainTabs` 缺失问题。
+- 低：远端 URL 不保留账号密码，认证信息只用于本次读取。
+- 高：Kyant0 Backdrop 的 `layerBackdrop` 捕获范围内不能再直接绘制使用同一 backdrop 的玻璃控件，否则可能形成循环渲染并在 RenderThread 触发 SIGSEGV；页面源层与玻璃控件必须分离，视频源层只包 AndroidView。
+- 中：远端提交与本地大范围未提交 UI 改动并行时，先暂存本地改动、合并远端非冲突文件，再恢复本地改动并手动吸收远端业务行为，避免整文件覆盖。
+- 高：Backdrop 的来源层与消费玻璃必须是同级兄弟层；菜单外部手势层也必须位于菜单内容下方，否则打开手势会误触发关闭。
+- 中：Backdrop 的玻璃效果是否明显取决于来源内容；纯白卡片上无法显示明显折射，需依靠仓库的高光、阴影和 lens 边缘表现，不能用普通白色背景冒充。
