Banoth-Rajesham/krupa-enterprises-ro-service ? reverse-engineered prompt

Build me a simple polished web app that works with Gemini and runs locally from a Vite project.

I want it to feel like a finished AI Studio app, with a clean landing page, a place for the user to type a prompt, and a nice response area that shows the AI output clearly. Make it easy to set up with a GEMINI_API_KEY in a local env file, and make sure it runs smoothly with npm install and npm run dev.

Please keep the design modern and responsive, with a friendly interface that looks good on desktop and mobile. If it helps, add a few helpful example prompts and basic loading and error states so it feels complete. Use current best practices and look up the latest docs online if you need to. I mainly want something that feels ready to deploy and easy to understand, not a rough prototype.
