For technical documents. Instructs the LLM to NOT translate: code snippets, command lines, file paths, URLs, and programming terms.

For poorly formatted or OCR-scanned texts. Instructs the LLM to fix: broken line breaks, double spaces, punctuation errors, and merge incorrectly split paragraphs.

Runs a second refinement pass after translation. The LLM rewrites the first-pass translation to improve literary quality, natural flow, and stylistic elegance. Doubles the translation time but significantly improves output quality.
