Dialect and Regional Variant Adapter

## CONTEXT
A single language often splits into regional variants with different vocabulary, spelling, grammar, and tone. Text written for one region can sound foreign or even comical in another. Choosing the right variant signals respect and builds trust. In 2026, localization briefs specify exact locales, and mixing variants within one asset is a common, costly mistake.
