"""
Hugging Face Spaces entrypoint for CognitiveKernel-Launchpad.
Defines a Gradio demo object at module import time as required by Spaces.

Environment variables are used for credentials when not provided in config.toml:
- OPENAI_API_BASE   -> used as call_target when missing in TOML
- OPENAI_API_KEY    -> used as api_key when missing in TOML
- OPENAI_API_MODEL  -> used as model when missing in TOML

Note: Although variable names say OPENAI_*, they are generic in this project and
can point to other providers such as ModelScope.

Additionally, we proactively ensure Playwright browsers are installed to avoid
runtime failures in Spaces by running a lightweight readiness check and, if
needed, invoking `python -m playwright install chrome`.
