DmitryMatv/classifast ? reverse-engineered prompt

Build me a web app where I can paste a product or service description and get the best matching classification codes back fast.

I want it to support standards like UNSPSC, ETIM, and NAICS at least, and if possible also HS and CN. The results should feel smart, not just keyword based, so rank the best matches first and show a confidence score for each one. Make the interface clean, responsive, and easy to use on desktop and mobile, with a simple homepage and separate pages for each classifier type.

It should also be SEO friendly, have good meta tags and structured data, and include a basic health check endpoint for deployments. Use modern web tooling and a Python backend if that makes sense. If you need to look up the latest docs for any library or deployment detail, go ahead and do that. Also make it container friendly so I can run it locally or deploy it easily.
