本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

契约
- Puppeteer 24.4.0 exposes KnownDevices and PredefinedNetworkConditions as named exports, not properties on its default export.
- KnownDevices has separate iPhone 15 portrait and landscape descriptors whose viewport uses isMobile, hasTouch, and isLandscape.
- PredefinedNetworkConditions['Fast 3G'] records download/upload throughput in bytes per second and latency in milliseconds.
- Copying a network preset before customization leaves the process-wide preset unchanged.
