1) 侧边栏对比度
   - 新增 --sb-* 专属色板（固定深色底，不随日夜主题翻转），文字 #c3d7e3、
     hover 纯白、选中纯白 + 品牌色强调条 + 内描边，参考 GoodJob 的 Command Deck
   - 原过渡曲线（--transition-fast/base）保持不变
   - luxury.css 里把侧栏刷回浅底的覆盖一并改为同一套色板

2) 顶栏「已打开页面」标签
   - 新增 src/navigation.js：NAV_GROUPS 与 PAGE_LABELS 单点维护，App 与顶栏共用
   - GlobalHeader 用 useLocation 自动登记访问过的页面，工作台恒定置顶且不可关闭，
     其余按最近使用排序，可单独关闭，最多 10 个，落 localStorage（happy.openTabs）
   - 关掉当前标签会退到剩下的最近一个，没有则回工作台

3) 折叠态页脚
   - .sidebar.collapsed .settings-btn 隐藏，76px 宽度下只留一个日夜切换按钮

4) 明月图标
   - MoonIcon → MoonStarsIcon，造型取自 igoutu.cn/icon/101343/moon-and-stars，
     重绘为矢量（月牙 = 两段圆弧相减，两枚凹边圆角四角星），走 currentColor 随主题变色
   - 源图存 design-refs/（已忽略，不入库）

5) 顶栏排布修正
   - 标签条加入后头部变挤，收窄品牌区/搜索框，按钮加 nowrap 防止文字折行
   - ≤1280px 隐藏标签条
