Avoid large layout shifts

2 layout shifts found

These are the largest layout shifts observed on the page. Each table item represents a single layout shift, and shows the element that shifted the most. Below each item are possible root causes that led to the layout shift. Some of these layout shifts may not be included in the CLS metric value due to windowing. Learn how to improve CLS

01 / 值得借鉴

好设计，具体好在哪

主题先于零散图片

Rooms Lit Only by Lamps 等主题卡同时展示拼图、作者和数量，帮助读者知道将进入哪类集合。

界面不抢图片注意力

白底、淡分隔和小字号分类让不同风格的摄影与平面作品可以同屏出现。

02 / 下一步

值得继续打磨的地方

  1. 01

    提示分类栏可以继续横向浏览

    手机分类只露出前几个条目，剩余分类依赖横向滚动。

    在分类末端提供轻量滚动提示或更多分类入口，保持已选分类在视野内，并验证键盘可以切换所有分类。

03 / 设计语言

数据来自同次页面采集；字体、圆角和间距为具体元素采样，不代表全站唯一设计规范。空值为未取得。HTML 为源码体积，不是压缩传输量；脚本数为 DOM 标签数，不是请求数。

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://cosmos.so 的 2026-09-05T03:19:32.193Z 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
搜索框与分类条在顶部，Selected by Cosmos 用横向收藏卡建立主题，Explore elements 展开多列图片。手机先保留搜索，再以横向分类和双列内容维持浏览密度。复刻重点是收藏层与单张素材层的差别、统一边距和图像比例，而非复制参考站的摄影素材。

验收
- 在 1440×900 和 390×844 分别核对文字、布局和主要操作“Sign up”。
- 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。
