+To keep the demo clear and reusable, it relies on the following components:
+- `prompt_builder.py`: builds the text prompt from the task instruction and action.
+- `visual_hint.py`: adds visual action hints (e.g. click circles or swipe arrows) to the input screenshot.
+- `render_utils.py`: post-processes generated HTML, renders it into an image, and saves outputs.

 ```
 pip install transformers==4.57.0
 ```
