18012961/Capitec ? reverse-engineered prompt

Build me a full stack loan eligibility simulator for Capitec style lending, with a Spring Boot backend and a simple HTML, CSS, and JavaScript frontend.

I want users to enter personal and financial details like age, income, employment length, loan amount, credit score, and loan term, then instantly see whether they qualify, along with any validation errors and a clear explanation of the result. It should also calculate an estimated interest rate based on the backend rules and scoring.

Please make the frontend pull the available loan products and purposes from the backend automatically, so the dropdowns update dynamically instead of being hardcoded. Keep the UI clean, modern, and mobile friendly, with a simple two column layout and nicely styled cards. If you need to check current Spring Boot or frontend best practices, feel free to look up the latest docs online.
