Nutrition Analyzer - Copy this React, Tailwind Component to your project

Create a modern and minimalistic single page web application using React and Tailwind CSS. The website should feature: A Black and White Theme: The entire site should have a sleek, professional look with a black background and white text, incorporating shades of gray for contrast. Introduction Animation: Implement a full screen introduction slide with a fade in effect that greets the user with the website's purpose (e.g., "Welcome to Nutrition Analyzer"). After a few seconds, this slide should transition smoothly to the main content. File Upload Section: After the introduction animation, present a file upload section where users can select an image file from their PC. Basic Animations: Include animations such as fade ins and slide ins to enhance user experience. Ensure that animations are smooth and subtle, adhering to the website's minimalist theme. Backend Communication: Once an image is uploaded, send it to a backend server for processing (the backend is assumed to be set up and running). Display the results (density, nutrition, and calories) received from the server.
