/// The prompt template used for evaluating the quality of a Cooklang conversion.
///
/// It instructs an LLM to compare a Cooklang conversion against the original
/// recipe text across ingredient coverage, quantity fidelity, step fidelity,
/// syntax, metadata, language, and token hygiene, and lists the failure modes
/// observed in production conversions. The model returns a JSON object with a
/// `good`/`bad` verdict, a 1-5 score, concrete issues, and a summary note —
/// matching the review taxonomy used by the cook.md admin quality page.
///
/// The prompt is loaded from `eval_prompt.txt` at compile time and contains
/// `{{ORIGINAL}}` and `{{COOKLANG}}` placeholders to be filled with
/// [`inject_evaluation`].
