   复用 public/index.html 的 CSS 变量，保证营销页 / 管理后台 / 客户门户
   三套界面品牌一致。**v2：所有界面统一为浅色主题**（白底深字，对齐 marketing 站）。

   排版规范（对齐 docs/UI-IA-SPEC.md §3 设计系统）：
   - 间距节奏：4px 基准（--sp-1..--sp-7），区块纵向节奏 16px / 24px
   - 圆角：卡片 14px，按钮/输入 10px，徽标/胶囊 999px
   - 阴影：卡片用 --shadow-sm，浮层（弹窗/选择器）用 --shadow-md
   - 层级：h1(22) > panel h2(16) > body(14) > 辅助(12.5) > 脚注(11.5)
