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
- useId returns colon-delimited strings like :R0: that ignore any prefix arguments passed to the hook and cannot be used directly in unescaped CSS ID selectors.
- Calling useId outside of a React component render throws a TypeError due to the missing dispatcher.
- Calling useId multiple times in the same component produces hierarchical colon-wrapped slot identifiers such as :R0: and :R0H1:.
- Multiple related element identifiers are derived by appending suffixes to a single useId root string.
