视觉系统主干落地：对齐 design tokens 与核心组件样式向 Zibll 收敛

- tokens：收紧 surface 层级/边框/圆角/阴影/间距与暗黑基线
- 组件：按钮、卡片原语、导航、侧栏、分页、模态、浮动按钮
- 首页：hero 外壳、fixed 列表/宫格、tab、skeleton/error 及各运营模块卡片化
- 内容页：单篇封面/标题/正文/blockquote/相关/TOC/上一篇下一篇、评论区
- 社区：forum board/topic/compose 子控件与卡片体系
- 交易/认证：cart/orders/revenue/product/auth 表面块与模态浮层统一
- footer：页脚主体、社交/联系、移动端 tabbar/搜索覆盖
