Multilingual support is not a translation project. It is a quality-control project across tone, policy accuracy, and resolution speed.

The second principle is style governance. Define how formal the assistant should be, how short answers should stay, and which terms should never be translated.
Language switching must be natural. If a user starts in English and moves to Turkish, the assistant should adapt without losing conversation memory.
Measure quality per language, not global average only. A strong EN score can hide weak TR performance and vice versa.
