+- 修复搜索结果表格显示异常：
+  - 问题：搜索只显示文件名（如 SimHei.ttf），缺少 Size、Last modified 列，且点击后 404。
+  - 根因：`render()` 直接把抓取到的 `tr.outerHTML` 拼进新表格，浏览器解析时 `<tr>` 不能作为 `<div>` 子元素，导致 `div.firstChild` 是文本节点，`href` 未正确替换，最终只渲染出孤立文件名。
+  - 修复：在 `theme/header.html` 和 `theme-preview.html` 的 `crawl()` 中改为提取结构化数据 `{ name, full, isDir, size, date }`，`render()` 手动生成完整 4 列表格行，并用 `escapeHtml()` 处理输出；链接统一用绝对路径 `full`，兼容 href 已以 `/` 开头的情况。
+- 修复搜索结果中目录名双斜杠：原 `render()` 对目录无条件追加 `/`，而 fancyindex 的链接文本本身已带 `/`，导致 `client-v1.3.7//`。改为仅在 `e.name` 不以 `/` 结尾时才追加 `/`。同步更新 `theme/header.html` 与 `theme-preview.html`。
+- 说明：Directory 面包屑显示的是当前页面 URL 路径，搜索时 URL 不变，所以面包屑保持当前目录路径是正确行为；点击搜索结果进入子目录后才会更新。
+- 新增「返回根目录」按钮：位于搜索框右侧，`.search-form` 改为 flex 布局，`.home-btn`（accent 色胶囊按钮 + home 图标 + 文字），href="/"；窄屏 (<=480px) 只显示图标。改动在 `theme/header.html`、`theme-preview.html`、`theme/css/styles.css`。
+- 新增「返回上一级目录」按钮：位于搜索框左侧，`initUpBtn()` 用 JS 根据 `location.pathname` 计算父目录并写入 `href`（如 /a/b/ -> /a/）。`.up-btn` 用 outline 风格（透明底 + border）与根目录实心按钮区分；窄屏只显示图标。改动同上三文件。
+- 修复「上一级」按钮不显示：`initUpBtn()` 原在 `file://` 预览或站点根目录时 `display:none`，导致预览和根目录页看不到按钮。改为始终显示：预览时 `href="#"` 仅展示；http(s) 下根目录 `href="/"`、子目录指向上级 `path.slice(0, idx+1)`。
+- 关键部署修正：`theme/header.html` 第 1 行的 CSS 链接原本指向远程 `https://repo.52or.com/fancyindex/styles.css`，导致本地 `theme/css/styles.css` 的样式（含 `.up-btn`/`.home-btn`）在服务器上不生效。已改为 `/theme/css/styles.css`，与 `fancyindex.conf` 的 `/theme/...` 约定一致，主题自包含。
+- 修复按钮被旧 CSS 缓存导致换行：截图显示「上一级」与「根目录」垂直堆叠、且输入框未同行，说明浏览器仍在用旧的（或未同步的）CSS，`.search-form {display:flex}` 未生效。给 CSS 链接加 `?v=3` 缓存戳，并在 `<form>` 上内联 `style="display:flex;justify-content:center;align-items:center;gap:10px;"` 作为兜底。同步更新 `theme/header.html` 与 `theme-preview.html`。

+# 2026-07-18 工作日志
+
+## 1. 诊断：部分 .zip 文件不显示
+- 现象：`Nginx-Fancyindex-Theme.zip` 不显示，`ServerStack.zip` 正常显示。
+- 根因：`fancyindex.conf` 第 8 行 `fancyindex_ignore "theme";` 本意是隐藏 `/theme/` 资源目录，
+  但 `fancyindex_ignore` 在 PCRE 下是**不区分大小写 + 未锚定的子串正则**（`ngx_http_fancyindex_module.c`
+  用 `NGX_REGEX_CASELESS` 编译，且按裸文件名匹配、无 `^$` 锚点），因此也命中了文件名含 `Theme` 的 zip。
+- 建议修复（尚未改动配置）：改为 `fancyindex_ignore "^theme$";` 精确匹配目录名，避免误伤含 theme 的文件。
+
+## 2. 修改：列标题改为 File Name / File Size / Date
+- nginx 的 `ngx-fancyindex` 模块自行生成 `table#list` 的 `<thead>`，主题无法用静态 HTML 改表头文字；
+  且 `styles.css` 的 `thead th { text-transform: uppercase }` 会把标题强制大写。
+- 方案：在 `theme/header.html` 的 IIFE 中新增 `renameHeaders()`，于 `onReady()` 调用，
+  用 JS 改写 `table#list` 与 `table.results` 的 `<th>` 文本为
+  `['File Name','File Size','Date','']`，并通过内联 `th.style.textTransform='none'` 覆盖大写（内联优先级高于外部 CDN 样式，无需改 CSS 文件）。
+- 同步更新 `theme-preview.html` 的静态 thead 与脚本，保持预览一致。
+- 注：`header.html:1` 仍引用外部 `https://repo.52or.com/fancyindex/styles.css?v=3`，本地 `theme/css/styles.css` 不一定线上生效；JS 内联方案不受此影响。
+- **回退**：用户要求"回退到上一个版本"，已将 `theme/header.html` 与 `theme-preview.html` 中本次的列标题改动全部撤销，恢复为 `Name / Size / Last modified`。主题文件当前回到改动前状态。

+# 项目长期记忆：Nginx-Fancyindex-Theme
+
+## 部署约定
+- 主题资源放在 nginx `root` 下的 `theme/`：`/theme/header.html`、`/theme/footer.html`、`/theme/css/styles.css`。
+- 依赖第三方 `ngx-fancyindex` 模块；未编译则 `fancyindex` 指令报错。
+- `fancyindex_ignore "theme"` 仅隐藏列表显示，不阻止对 `/theme/...` 的直接访问。
+
+## 已知坑
+- 搜索结果显示需手动构建表格行：不可依赖抓取到的 `tr.outerHTML` 直接插入新表格，否则会出现列缺失、链接错误、只显示文件名等问题。应提取 `{ name, full, isDir, size, date }` 结构化数据后重新渲染 4 列表格（Name / Size / Last modified / 空）。
+- `header.html` 中 CSS 链接、目录路径清理、搜索递归均用前端 JS 实现，修改后刷新页面即可生效，无需 reload nginx。
