🔧 How It Works

1. The user sends a product URL to the /scrape endpoint.
2. Puppeteer launches a headless browser and navigates to the URL.
3. The page content is retrieved and loaded into Cheerio for HTML parsing.
4. Helper functions extract product details such as title, price, availability, images, reviews, and ratings.
5. The data is structured and returned as a JSON response via the API.
