// @evidence contracts/testing.md#distinguishing-cases CRLF outer/template lines retain their exact spelling; mixed and other ECMAScript separator hosts own broader boundaries.
// @evidence contracts/testing.md#execution-ownership TestUnicornTemplateIndentPreservesCRLF owns its explicit variants and named subcases as a discoverable Go unit entry; real parser/engine snapshots and disk fix application compare literal CRLF output and clean re-lint in the Go test process; no installed consumer, native producer or product child host runs.
