hrd-pensiun/Karatak — reverse-engineered prompt

Build me a simple web app called Karatak for cataract screening. I want it to feel like a clean medical dashboard where a clinic worker can enter basic patient info, upload or preview an eye image, then get an easy to understand cataract assessment with a risk level, short explanation, and suggested next steps like monitor, refer to doctor, or urgent checkup.

If there isn’t a real AI model or API set up yet, make the analysis flow work with realistic mock results so the app is still usable for a demo. Please include a polished landing or main screen, clear buttons, loading state, result card, and a way to reset and check another patient. Keep the design professional, responsive, and friendly for non technical users.

Use the existing JavaScript app setup and make sure it runs locally without errors. Look up current docs online if you need to.
