/* =============================================================
   VectorShop 官网 v2 设计系统(参照 paper.design)
   规划:Docs/2026-10-16-site-redesign-paper-style-plan.md
   组件样张:Site/redesign/components.html(本地看,不上线)

   结构:
     1. 字体与 token(浅色 / 暗色,跟随系统)
     2. 基础与排版
     3. 画板栏、分段、格子
     4. 母题:标尺、锚点、贝塞尔拱、方格纸、选中框
     5. 组件:导航 按钮 标签 作品卡 对比 窗口/终端 标签页 规格 定价 FAQ 表格 表单 正文 页脚
     6. 窄屏与减少动态

   规则:组件只用 token,不写字面颜色;暗色只重定义 token。
