- Настроена среда на Ubuntu 24.04: проверены Node.js и PostgreSQL, выполнен npm run install:all.

- Пересобран bcrypt под Linux (npm rebuild / переустановка), после чего успешно отработал prisma seed (созданы пользователи и загружены СБЦ).
- Создано виртуальное окружение backend/pdf_generator/venv и установлены зависимости из requirements.txt; backend настроен использовать python из этого venv при генерации PDF (pdf-python.service.ts).
- Переключён AI-провайдер с LMStudio на Ollama: в ai.service.ts добавлена поддержка Ollama, в .env и .env.example выставлены AI_PROVIDER=ollama, OLLAMA_API_URL=http://192.168.88.160:11434 и OLLAMA_MODEL=gemma3n:e4b.
- Перезапущены backend и frontend; проверено, что API /api/health отвечает, а Ollama (gemma3n:e4b) успешно обрабатывает chat-запросы.

-Для корректного отображения кириллицы в PDF положите сюда TTF-шрифты с поддержкой русского языка.
+Для генерации PDF с кириллицей используются шрифты PT Sans из npm-пакета `@fontsource/pt-sans` (файлы в `node_modules/@fontsource/pt-sans/files/`).
 
-**Варианты:**
+При необходимости можно положить сюда свои TTF/WOFF (например, PTSans-Regular.ttf и PTSans-Bold.ttf) — тогда в `pdf.service.ts` нужно указать путь к этой папке через `path.join(process.cwd(), 'fonts', '...')`.
-
-1. **PT Sans** (рекомендуется, лицензия OFL)  
-   Скачайте с [Google Fonts](https://fonts.google.com/specimen/PT+Sans) и поместите в эту папку:
-   - `PTSans-Regular.ttf`
-   - `PTSans-Bold.ttf`
-
-2. **Arial**  
-   На Windows можно скопировать из `C:\Windows\Fonts\arial.ttf` (и при необходимости arialbd.ttf для жирного).
-
-3. Любой другой TTF с кириллицей (например, DejaVu Sans, Open Sans).

+<#
+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies:

+BLP1 files, used mostly in Warcraft III, are not fully supported.
+All types of BLP2 files used in World of Warcraft are supported.
+
+The BLP file structure consists of a header, up to 16 mipmaps of the
+texture
+
+Texture sizes must be powers of two, though the two dimensions do
+not have to be equal; 512x256 is valid, but 512x200 is not.
+The first mipmap (mipmap #0) is the full size image; each subsequent
+mipmap halves both dimensions. The final mipmap should be 1x1.
+
+BLP files come in many different flavours:
+* JPEG-compressed (type == 0) - only supported for BLP1.
+* RAW images (type == 1, encoding == 1). Each mipmap is stored as an
+  array of 8-bit values, one per pixel, left to right, top to bottom.
+  Each value is an index to the palette.
+* DXT-compressed (type == 1, encoding == 2):
+- DXT1 compression is used if alpha_encoding == 0.
+  - An additional alpha bit is used if alpha_depth == 1.
+  - DXT3 compression is used if alpha_encoding == 1.
+  - DXT5 compression is used if alpha_encoding == 7.
