streamgeeks/visual-reasoning-playground ? reverse-engineered prompt

Build me a polished web playground for AI powered visual reasoning tools for broadcast and live streaming people.

I want one site that shows a bunch of interactive demo pages for things like scene description, object detection boxes, gesture based OBS control, smart counting, scene analysis, zone alerts, color matching, multimodal audio plus video triggers, and PTZ camera tracking style tools. It should feel like a real product demo hub, with a homepage that lets me jump into each tool, short explanations for each one, and working playground mode so it still runs with sample video even if there is no camera connected.

Make it look clean and modern, and keep it easy to try online in a browser. If any current API or integration details are needed, look up the latest docs online and wire it up in a simple practical way. I also want the app to be organized so each demo lives on its own page and can be expanded later.
