cam-hm/jarvis ? reverse-engineered prompt

Build me a web based JARVIS style voice assistant that feels like talking to Iron Man’s assistant.

I want a dark, futuristic page with a glowing Arc Reactor style center piece that animates while the assistant is listening and speaking. It should let me type a message or click a microphone button and talk, then show the reply on screen and read it back out loud with a British sounding JARVIS voice. The assistant should use Gemini for the brain, and it should respond in real time so the conversation feels fast and alive.

Make it run locally, be easy to start with one command, and work well in Chrome. If you need current docs for any of the APIs or libraries, look them up online first. Also make it feel polished, with neon purple and cyan styling, smooth motion, and a clean layout that looks like a real sci fi dashboard rather than a plain chatbot.
