   ------------------------------------------------------------
   端口自 design-handoff prototype/shell.css。
   ⚠️ 已删除 :root token 定义块（token 现由 /assets/anlan-tokens.css 单一真源提供）。
   ⚠️ 已删除共享 chrome（.nav / .breadcrumb / .footer）——这些也在 anlan-tokens.css。
   本文件只保留用例库专属组件：base reset + wave 背景 + 按钮 + section + uc-card +
   迁移矩阵 + 风险面板 + Agent Spec + facet 筛选 + hero 搜索/chips 等。
   配色全部沿用 token 变量，dark/light 自动切换。
