Render-blocking requests

Est savings of 580 ms

Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.

01 / 值得借鉴

好设计，具体好在哪

观点标题直接形成品牌

Small teams、Work isn’t war 等短句无需插画就传达公司的鲜明态度。

编号让长目录有秩序

每行都以两位编号开头，读者能够辨认相邻章节与整体阅读进度。

02 / 下一步

值得继续打磨的地方

  1. 01

    避免目录渐隐削弱可读性

    首屏底部几条观点逐渐变淡，虽然暗示后续内容，也降低了文字对比。

    将渐隐只用于滚动容器边缘，当前可选条目保持足够对比；键盘聚焦时立即显示完整文字。

03 / 设计语言

没有 HSTS 响应头

中优先级

没有 Strict-Transport-Security，第一次访问仍可能被降到 http。浏览器不会钉死 HTTPS。

在边缘设置 Strict-Transport-Security: max-age=31536000; includeSubDomains。

strict-transport-security missing

没有 Content-Security-Policy

CSP 是限制脚本源的标准做法。vibe 页面常常什么都加载，包括被注入的脚本。

先开 report-only CSP，再收成 default-src 'self' 和明确的 script-src。

content-security-policy missing

没有 X-Content-Type-Options

没有 nosniff，浏览器可能按错误类型解释文件。这是一行响应头。

设置 X-Content-Type-Options: nosniff。

x-content-type-options missing

没有 Referrer-Policy

默认 referrer 可能把站内路径和查询串漏给第三方。

设置 Referrer-Policy: strict-origin-when-cross-origin。

referrer-policy missing

请基于 https://37signals.com 的 2026-09-05T03:26:03.910Z 页面快照优化当前项目。先确认当前实现与快照差异，不要把已变化的内容重新改回旧版。

设计基线
顶部连接 Basecamp、HEY、Fizzy 与 ONCE，主体以从00开始的观点目录组织公司理念，底部聚合书籍、文章、招聘和政策。手机仍以单列编号为主体。参考单一强色、统一编号和密集目录的节奏；需要为长目录提供清楚的当前项与返回路径。

执行事项
1. 避免目录渐隐削弱可读性
将渐隐只用于滚动容器边缘，当前可选条目保持足够对比；键盘聚焦时立即显示完整文字。
依据: desktop.png and mobile.png: lower index entries fade

2. 没有 HSTS 响应头
在边缘设置 Strict-Transport-Security: max-age=31536000; includeSubDomains。
依据: strict-transport-security missing

3. 没有 Content-Security-Policy
先开 report-only CSP，再收成 default-src 'self' 和明确的 script-src。
依据: content-security-policy missing

4. 没有 X-Content-Type-Options
设置 X-Content-Type-Options: nosniff。
依据: x-content-type-options missing

5. 没有 Referrer-Policy
设置 Referrer-Policy: strict-origin-when-cross-origin。
依据: referrer-policy missing

验收
- 在 1440×900 和 390×844 分别核对文字、布局和主要操作“00. Start here”。
- 保留已有品牌、登录和业务链路，不从静态截图推断交互故障。
- 只修复有证据的项；涉及安全响应头时先用报告模式验证现有资源及认证兼容性。
- 对比修改前后的截图，并执行相关功能测试。不要声称未经测试的功能已通过。
