 ## Architecture
 
 - **core.py** — Pure Python, no GUI dependencies. Parses .NET BinaryFormatter (NRBF) save files, finds field offsets, patches binary data in-place.
-- **ui.py** — Flet-based GUI. Uses `FilePicker` for file selection, `TextField` for inline editing. Runs on desktop; future-proof for mobile/web.

+## Архитектура

+- **core.py** — Чистый Python, без GUI-зависимостей. Парсит .NET BinaryFormatter (NRBF), находит смещения полей, патчит бинарные данные inplace.
+- **ui.py** — GUI на Flet. Использует `FilePicker` для выбора файла, `TextField` для inline-редактирования. Работает на десктопе.
