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
- Accessing LazyResult.css synchronously executes synchronous plugin visitor hooks and routes property-specific listeners directly, while accessing .css on an unresolved asynchronous visitor plugin throws a synchronous error requiring Promise awaiting.
- Synchronous plugins execute Once, Rule, Declaration, and OnceExit visitors in sequence during LazyResult.css evaluation.
- Targeted Declaration listeners defined by property name (e.g. Declaration.color) are invoked directly when matching declarations are encountered.
- Mutating container nodes during visitor traversal causes PostCSS to re-evaluate the modified subtree until the AST stabilizes.
- Synchronous access to LazyResult.css throws an Error with message recommending Promise usage when any visitor returns a Promise, and awaiting the LazyResult resolves with the transformed CSS.
