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
- assert yoga-layout resolved version is 3.2.1
- assert default Config has useWebDefaults disabled (false) and default Node uses React Native defaults (flexDirection Column, flexShrink 0, alignContent FlexStart)
- assert Config with setUseWebDefaults(true) sets web defaults (flexDirection Row, flexShrink 1, alignContent Stretch)
- assert child Node does not inherit Config from parent upon insertion and retains flexShrink 0 unless created with the Config
- assert overflowing children in a fixed row fail to shrink under Yoga defaults (overflowing container to 300px width)
- assert overflowing children in a fixed row shrink to fit (100px each, 200px total) when created with useWebDefaults Config
- assert pointScaleFactor 1.0 rounds coordinates to integer pixel boundaries (10.6 to 11 and 10.4 to 10)
- assert pointScaleFactor 0.0 disables pixel snapping and preserves exact subpixel floating point values
- assert pointScaleFactor 2.0 snaps coordinates to half-pixel multiples (10.25 to 10.5 and 10.75 to 11.0)
- assert freeing root node with freeRecursive releases entire tree and Config.free releases config allocation
