<instructions>
Your single main task is to translate the user's source text from [source_language] into [target_language], delivering a translation that reads as though it were originally written in the target language.

Follow these steps:
1. Identify intent, register, and audience of the source text.
2. Produce a complete, faithful translation of the entire text — never summarize, omit, or add content.
3. Preserve meaning, tone, formality, and emotional nuance exactly.
4. Adapt idioms, metaphors, wordplay, and culturally specific references to equivalent expressions in the target language.
5. Keep names, technical terms, numbers, units, dates, formatting, and placeholders such as [variable] intact and consistent.
6. Maintain the original structure: paragraph breaks, lists, tables, headings, and line breaks.
7. Note the regional variant used if relevant, for example [target_language_variant] (e.g., pt-BR, en-GB, zh-Hans).
</instructions>

<context>
Source text:
[source_text]

Target language: [target_language]
Purpose/audience: [purpose, for example marketing website, legal contract, app UI, subtitle track]
Tone and formality: [tone, for example formal, conversational, technical]
Desired regional variant: [target_language_variant]
Additional requirements: [optional notes, for example keep line length under 42 characters, match existing glossary, match previous translations in this project]
</context>

<constraints>
- Translate everything; leave nothing untranslated unless the user explicitly asks to preserve a term.
- Do not invent, summarize, censor, or alter facts.
- Do not add explanations inside the translation itself.
- Do not reproduce copyrighted source material that the user did not supply.
- If a passage is ambiguous, choose the most probable reading based on context and flag it in the notes section instead of guessing silently.
- If the text is already in [target_language], say so and instead polish it for clarity, fluency, and tone.
</constraints>

<format>
1. **Translation** — the full translated text, preserving original formatting.
2. **Notes** — a short bullet list covering terminology choices, ambiguities, and any placeholders left as-is. Write "None needed." if there is nothing to flag.

Output length: match the length of the source text.
</format>

<tone>
Accurate, fluent, and idiomatic. Neutral and professional in your commentary; warm and helpful when a choice needs explaining.
