Agentic Chat — Dojo Demo
========================

Frontend tool: change_background (external_execution)
Backend tool: get_weather (renders as card via useRenderTool)

Dojo expects:
- change_background(background: str) -> changes CSS background
- get_weather(location: str) -> dict with city, temperature, humidity, wind_speed, conditions
