用户要求把主栏界面改成米白色。这应该是指把「全部曲谱」和「收藏曲库」的主内容区域背景从深色改成米白色（cream/off-white），同时保持红黑配色的整体风格。这意味着需要调整：
1. 主内容区的背景从深色（#0D0D0D）改为米白色（如 #F5F0E8 或 #F7F3EC 之类的暖米白色）
2. 相应的文字颜色需要从浅色改为深色
3. 五线谱纹理需要调整颜色以适配米白背景
4. 卡片背景需要调整
5. 分隔线等元素需要调整
但需要保持整体的复古黑胶美学和装饰艺术风格。米白色作为主内容区背景，搭配深色文字和复古红点缀。
让我重新思考设计：
- 主内容区背景：米白色（warm cream），如 #F7F2EB
- 文字颜色：深色 #2A1A1D 或 #1A0D0F
- 辅助文字：中灰色调
- 五线谱纹理：用浅红/淡红线条
- 卡片：浅色带红边框
- 黑胶唱片仍然保持深色（对比）
- 导航栏和状态栏保持不变（深色）
这样形成深色顶部导航 + 米白内容区 + 深色底部导航的经典布局。
顶部导航栏和底部导航栏应该保持深色不变（#0D0D0D / #0A0A0A），只改中间的内容区域。
让我重新构建样式。同时需要注意：
- 收藏曲库的卡片也需要改成适配米白背景的样式
- 黑胶唱片在米白背景下会更突出
- 字体颜色需要反转
- 分隔线颜色需要调整
同时用户可能还希望整体风格上做调整。让我仔细处理。
另外，"主栏界面"可能也包含导航栏？我觉得用户说的是主要内容区域，即两个Tab页面的内容区。但为了保险起见，我重新审视：也许用户希望整个应用包括导航栏都改成米白色？不过那样就和"纯红黑配色"的原始要求冲突了。我倾向于理解为：主内容区（两个Tab的内容面板）背景改成米白色，顶部导航和底部导航保持深色。
让我更新CSS变量和具体的背景色、文字色。五线谱纹理需要在米白背景上表现为淡红色线条。
此外，装饰艺术分隔线也需要调整颜色以在米白背景上可见。
歌曲列表项的边框也需要调整。
黑胶唱片在米白背景下会很好看，形成强烈对比。
让我构建这个版本。我会保持：
- 状态栏：深色
- 导航栏（logo + 设置按钮）：深色
- 装饰艺术分隔线：深色
- 主内容区：米白色
- 底部导航栏：深色
米白色选择 #F4EFE8 或 #F7F2EC，一个温暖的、带一点点泛黄的米白，符合复古美学。
五线谱纹理在米白背景上用低饱和度的淡红线条：rgba(139,45,58,0.15) 之类。
文字颜色：深棕红 #2A1518 或 #1A0D0F。
卡片背景：稍微深一点的暖色，如 #EDE7DF，带红边框。
黑胶唱片CSS保持不变（深色）。
好，开始构建。

将主内容区（全部曲谱 + 收藏曲库两个Tab面板）背景从深黑改为温暖米白色（#F5F0E8），文字色反转为深棕红，五线谱纹理改为淡红弱化线条，黑胶唱片保持深色与米白形成对比，收藏卡片改为暖灰底红边框，顶部导航栏与底部导航栏维持深色不变，整体形成深-浅-深经典三段式复古布局。
