前端（新增 ui/yohaku/，各视图按 ui_id=vivid 分支渲染；classic 与后台不受影响） - 令牌层：设计稿数值原样落地，28 个 --v-* 为站主接口（自定义 CSS 可覆盖， 放 @layer 让出优先级）；另加防线，中和 styles.css 裸选择器 （h1 衬线 / body 行高 / 后台 .stat/.toolbar/.chip 卡片）漏进余白元素 - 顶栏（滚动收缩态）/ 阅读进度（顶部 2px + READ n%）/ 页脚 - 首页：hero（统计条）/ 筛选（类型分段 + 标签 chips + 搜索）/ 长文卡片与短文纸条 / 分页 / 作品展示区（3 件 + 查看所有，参照 diygod.cc）； 面板栅格改 1.6fr 1fr 1fr 且高度自适应内容（标签云明显大一圈） - 文章页：三栏「纸」—— 左时间线（前后各两篇）/ 中纸张 / 右目录与阅读进度； 短文详情不显示标题（h1 视觉隐藏保留无障碍） - 全部规则收敛在 html[data-ui='vivid'] 前缀下；无 !important 后端 - GET /api/posts/:slug 增 neighbors（前后各两篇，详情页侧栏时间线用） - SPA 缓存头：index.html no-cache，assets/ 带 hash 长期 immutable （此前无缓存头，浏览器会一直拿旧构建） 其他 - 站主自定义 CSS 管线（customCss.js + ui/sections.js，按分区注入，仅 vivid） - 删除旧 vivid 覆盖层实现（VividNav/Hero/Footer/Timeline/Toc、ui/vivid.css） - 设计稿原型附于仓库根 index.html；作品表清掉外链 diygod.cc 的示例封面， 改用本地占位图（public/covers/）
