Translate to Russian (русский язык).

Language code: ru.

---

Use a neutral tone (not overly formal or informal).

Use correct Russian grammar — appropriate cases, suffixes, and endings depending on context.

For the following technical terms, use these specific translations to ensure consistency and clarity across the documentation:

* 🌐 Add Russian translation for `docs/ru/docs/tutorial/security/oauth2-jwt.md`. PR [#10601](https://github.com/fastapi/fastapi/pull/10601) by [@AlertRED](https://github.com/AlertRED).
* 🌐 Add Russian translation for `docs/ru/docs/tutorial/security/simple-oauth2.md`. PR [#10599](https://github.com/fastapi/fastapi/pull/10599) by [@AlertRED](https://github.com/AlertRED).

2. **Search/Analysis Support** (40+ languages): Language-specific text analysis for search indexing

Currently supported UI languages: German, English, Spanish, French, Italian, Japanese, Korean, Dutch, Polish, Brazilian Portuguese, Russian, Simplified Chinese, and Traditional Chinese.

- If the language to which you translate mostly uses the letters of the ASCII char set (for example Spanish, French, German, but not Russian, Chinese) and if the translation of the full phrase is identical to, or starts with the same letters as the original full phrase, then only give the translation of the full phrase.
