This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- transform with cssModules.pure set to true throws a SyntaxError stating that a selector in CSS modules should contain at least one class or ID selector when encountering impure element selectors
- transform with cssModules.pure set to true compiles successfully when every selector contains at least one class or ID selector
- transform with default cssModules configuration (pure: false) compiles impure element selectors without throwing an error
- exports maps each scoped class and ID to an object containing name, composes, and isReferenced rather than a bare string
