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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. parse parses CSS strings into AST with StyleSheet root and AST node structures
  2. walk traverses AST nodes and supports visitor callbacks and visit node type filters
  3. find finds the first AST node matching a predicate function
  4. generate serializes AST nodes back into standard CSS text
  5. lexer validates CSS property declarations and returns error status
  6. toPlainObject converts AST structures into plain JavaScript objects
  7. fromPlainObject reconstructs AST structures from plain JavaScript objects
  8. clone creates deep clones of AST nodes
