1"""Regression tests for validate-tokens.cjs.
2 
3The validator used to skip any line containing ``var(--`` outright, so a
4hardcoded value sharing a line with a token reference (extremely common in
5real CSS, and universal in minified CSS where everything is one line) went
6undetected. These tests drive the CLI via ``node`` and assert it flags such
7cases. They are pytest-based so the repository's existing pytest CI runs them.
