-## Translation Style
+**Audience**: {audience description}
 
 **Target style**: {style description — e.g., "storytelling: engaging narrative flow, smooth transitions, vivid phrasing" or custom style from user}
 
-**Source voice** (from analysis, if exists): {Describe the original author's voice — e.g., "Self-deprecating, conversational tone with frequent tech-industry humor. Sarcasm used to critique trends. Short punchy sentences alternate with longer analytical passages." Include: formal/conversational, humor type, cultural register, sentence rhythm, any distinctive patterns.}
-
-Apply the target style consistently while respecting the source voice. The translator should understand what the original sounds like in order to produce a translation that captures the same feel in the target style. Style is independent of audience — a technical audience can still get a storytelling-style translation, or a general audience can get a formal one.

-| {source metaphor} | {what the author actually means} | {Interpret / Substitute / Retain} | {target-language rendering or guidance} |

-Also note any emotional connotations (words carrying subjective feeling beyond dictionary meaning) and implied meanings (sentences where surface meaning is simpler than the author's full intent) identified in the analysis — preserve these in translation.

 ## Translation Principles
 
+Rewrite the content into natural, engaging {target_lang} — not merely translate it. Every sentence should read as if a skilled native writer composed it from scratch.
+
 - **Accuracy first**: Facts, data, and logic must match the original exactly
-- **Meaning over words**: Translate what the author means, not just what the words say. When a literal translation sounds unnatural or fails to convey the intended effect, restructure freely to express the same meaning in idiomatic {target_lang}
-- **Figurative language**: Interpret metaphors, idioms, and figurative expressions by their intended meaning. When a source-language image does not carry the same connotation in {target_lang}, replace it with a natural expression that conveys the same idea and emotional effect. Follow the Figurative Language Mapping table above for pre-analyzed decisions
-- **Emotional fidelity**: Preserve the emotional connotations of word choices, not just their dictionary meanings
-- **Natural flow**: Use idiomatic {target_lang} word order and sentence patterns; break or restructure sentences freely when the source structure doesn't work naturally
-- **Terminology**: Use glossary translations consistently; annotate with original term in parentheses on first occurrence
+- **Natural flow**: Use idiomatic {target_lang} word order. Break long source sentences into shorter, natural ones. Interpret metaphors and idioms by intended meaning, not word-for-word
+- **Terminology**: Use glossary translations consistently. Annotate with original in parentheses on first occurrence of specialized terms
 - **Preserve format**: Keep all markdown formatting (headings, bold, italic, images, links, code blocks)
-- **Respect original**: Maintain original meaning and intent; do not add, remove, or editorialize — but sentence structure and imagery may be adapted freely to serve the meaning
-- **Translator's notes**: For terms or cultural references listed in Comprehension Challenges above, add a concise explanatory note in parentheses. Use the provided reasoning to judge annotation depth — explain more for genuinely obscure references, less for terms that are merely unfamiliar. Only annotate where genuinely needed for the target audience.
+- **Proactive interpretation**: For jargon or concepts the target audience may lack context for, add concise explanations in **bold parentheses** `（**解释**）`. Keep annotations few — only where genuinely needed
