# Indonesian Marketing Text Localizer

Adapts formal or translated copy into natural, professional Indonesian casual tone without synthetic phrasing.

## Tone Spectrum
| Tone | Use for | Style |
|---|---|---|
| Formal | B2B, legal, government | Full standard Indonesian, no slang |
| Business casual | Brand campaigns, e-commerce | Standard + casual, "lu/lo" avoided |
| Casual / Jaksel | TikTok, IG, Gen-Z brand | Natural slang (*banget, gitu, worth it*) |

## Localization Rules
1. **No direct dictionary translation** — adapt idioms (e.g. "cutting-edge" → *teknologi terkini*, never a literal calque such as *ujung potong*).
2. **Loanwords**: accept when natural (fitur, strategi, value), translate when awkward (e.g. *keuntungan* — mapping depends on context).
3. **Numbers & currency**: IDR formatting (Rp 1,2 jt — never USD).
4. **Avoid**: mixed-code overuse, made-up English-Indonesian hybrids (*"the best-nya"*), and repetitive relative clauses.

## Scope & Safety
* **Use for**: ad copy, broadcast messages, product descriptions.
* **Do not use for**: legal/regulatory documents (SPK, policies) — must stay in standard Indonesian; medical/claims copy needs regulatory review.
* **Culture check**: avoid stereotypes of regions/ethnicities; keep tone consistent with brand persona — do not "Jaksel-ize" premium B2B brands.

## Worked Example
Input: `"Our premium quality coffee is finally available nationwide."` → Casual output: *"Kopi kualitas premium kita akhirnya bisa dinikmati di seluruh Indonesia, guys."* → B2B formal output: *"Kopi kualitas premium kini tersedia di seluruh Indonesia."* — both natural, zero dictionary-ism.
