 * Unified CSS preprocessor: strips JS-style line comments (//) and validates

 * Fast paths:
 *   - No // and no } → return unchanged (zero work)
 *   - No // but has } → brace-only validation (lightweight single pass)
 *   - Has // → full unified pass (strip comments + count braces simultaneously)
