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
- valueParser(value) parses CSS value strings into an AST with top-level and nested nodes
- valueParser.unit(value) extracts numeric quantity and unit suffix from CSS dimension strings
- valueParser.unit(value) returns false for non-numeric or unparseable input
- valueParser.walk(nodes, callback) traverses AST nodes recursively in top-down order
- valueParser.walk(nodes, callback) stops descending into child nodes when callback returns false
- valueParser.walk(nodes, callback, true) traverses AST nodes in bottom-up order when bubble is true
- valueParser.stringify(nodes) converts AST nodes back into a CSS string representation
- valueParser.stringify(nodes, custom) transforms serialized output using a custom node replacer function
