# Change: Add digital human script batch generation

## Why

Digital human creation currently supports one script at a time. Operators need to generate or add multiple talking-head scripts, then create several digital human videos from the same avatar, voice, and model configuration without repeating the form.

## What Changes

- Add a script list to the digital human one-click compose flow, supporting manual single-script addition and multi-script batch editing.
- Add an intelligent script generation dialog with built-in industry-style digital human talking-head scenes, word/time/style/count controls, and custom prompt input.
- Append generated script results into the script list instead of replacing existing work.
- Allow batch creation of digital human tasks, creating one runtime task per selected script while reusing the selected avatar, voice, model, subtitle, format, and background settings.

## Impact
