Build me a sleek skincare app called NURA that scans a person’s face in the browser using the webcam, then gives a simple skin assessment and a routine to follow. It should feel clinical and polished, with a modern landing page, a clear scan flow, animated results, and a friendly explanation of what each score means, like redness, texture, hydration, and shine.

The important part is that everything stays on the device. No uploads, no server, no saving photos, just analyze the camera frame locally and discard it. If the camera is unavailable, let the user upload a photo instead. After the scan, show the weakest areas first and recommend a routine from a built in product list, always ending with SPF. Please make the app fully responsive and ready to run as a static site, and look up current docs online if you need to.
