# 🆕 Setup Extensions: Host + Options Support

The **Setup Extensions** system now supports extended script metadata in the header.  
This allows script authors to define dropdown menus and control how the script is executed.

- **Default:** `embedded` (if not specified).

### `# Options: value1; value2; value3; ...`
